Mistreated at Old Mutual -Gateway

Good evening,my name is Thembelihle Mthembu, On Monday the 18th I went to the branch at Old Mutual -Gateway because I had an recently received information that the policy I'm I benefiery too was paid to a wrong person,when I arrived the the receptionist refused me entry saying that I should disclose the purpose of my visit, I was the first person that day but she was allowing everyone who came after me in and giving them tickets to enter, she then demanded to see my documents and also forced me to tell why I'm here as she said that she is part of the company and she has the right to know,,,,okay as I laid all my documents explaining my situation almost in tears because as I answered her questions she didn't even look at me but she was busy with her wave and all she did was to sign after pouring my heart out as I have lost my mother in law and my spouse on the same day , it's still a very sensitive issue for me, I felt so small , degraded and Soo disrespected and humiliated,when nearly 15-20 minutes explaining with the hope that I will allowed to see an agent,,But she Boldly told me to go as the documents I'm carrying are old,she to re satify the documents for a new date,,,, I was so heartbreaking and I left in tears, even after I had explained that I dont need to be checked in the system but all I needed was someone who will listen to me and give me a way forward, but she still insteaded that I leave and she told me that no one will help me. I came came last week Thursday and when I arrived I told I'm back regarding the same issues as last week -she didn't even wait for me to finish and she said that she wants hard copies and if I don't have them I must leave,,,,I was like no not again and she if I don't have hard copies I must leave,,,,I then said to her ,,,fine I am now changing the purpose of my visit I now want to open a account and she said I must stop lying ,,I stood there and insisted until she gave me the ticket,,when my number was called she had the odiserty to call the agent was going too and telling him to double check if my query matches what's on the ticket,,, before I could sit down I explained to the agent the today is the second time I have come and in both instances the receptionist keeps turning me away and today I now had to come through false enter as my query is not valid according to her,,,, the agent was very helpful as indeed my query didn't even need the branch, the agent referred me to the relevant department and he also arranged a call for me,,,,then the call got disconnected and I was now running late for work, I then went back to the agent to express my dissatisfaction towards the receptionist and the response was that we are sorry but we will talk to her. In my way out I went to her to try and speak to her regarding the way she had treated me in both occasions but because of the hurt I was in ,I end up taking her wave off and forcefully came and grabbed me so hard and because she was pushing me to a wall, I had no choice but to push back aswell. The mangers came they listened to my side of the story But still no one opened a complaint for me ,they kept me it the store until I requested a manager because now I didn't understand if I was detained or what,,,,after 10-15 minutes the said to write my details down and they said I must go,,, they wanted my name ,last name ,phone and where I work and my bosses number,,,, offwhich I all provided, Friday I received a very unprofessional call , firstly they called me by an incorrect name and when I said it must be a wrong number,the man who called me shouted in the background the girl is saying it's a wrong number,,,, someone else shouted back insisting that it's the right person,,the then proceeded to say that I am summoned to Durban North and I must be there at 8, and he asked if I heard or not ,,,I confirmed that I heard as he came across so intimidating and when I asked I was told to be there,,,before he dropped the call I asked him ,that when I arrive there who will I ask for,,and he answered Nxumalo,.....when I called the number back as I now realized that something is off ,no one answered the call and when I went to Truecaller the number is registered under someone else,,,,I now feel so unsafe and I'm now realizing that Old Mutual has give out my personal information against my consent and that's DPA Bridge,, please advise forward, I'm confused and scared as I'm now a single mother to 4 children and have no support system interms of raising my children as I have lost my mother in law and my spouse who supports us and protected us aswell
