WORST SERVICE FROM MTN AND MY INFORMATION BEING GIVED TO THE 3RD PARTY

Acc No:BA***:last month I got a call from a lady who I assume was calling from MTN telling me that my package which was Made for me XS is now changed to Mega talk XS as MTN no longer offer customers made for me XS and all the customers that are on Made for me XS will be migrated to this new package. Later on to only to find out that my information is given to the 3rd party by MTN to change my package without my knowledge or concern. When I find out a week later I called MTN customer service to ask them that I did not agree to anything as nothing was explained to me, so I request that my package will be changed to the previous package which it was Made for me XS.This is the references *** and *** that I got from the agent told me that it will be resolved and I will received the call from MTN staff, until today they still investigating and I have not receive any feedback. I was told to contact the 3rd party and they will investigate, and I did call them holding a line for 1hour just to speak to the consultant and the feedback that I got from them is that they don't have access to make changes on my account I must call MTN. I have been treated like an idiot,transfered from pillar to post, call being dropped by MTN agents while I am explaining. What I want to find out since I have signed 24 month contract with MTN ,how is that my information is being sold to 3rd party to do changes on my account but MTN cannot do what I am requesting them do. I am talking about my sensitive information like my ID:NO and banking details. I called again today to find out how far are they to resolve my issue and the agent Zandile told me that the issue is still open and its taking long because they cannot access recording, while I have a contract with MTN not the 3rd party.so I guess I am treated like a **** or MTN does not own my account anymore because MTN sold my information to 3rd party. I received my statement this month and I will be paying R840 instead of R799 that I signed with MTN,my hard earned money. I wonder how many customers are going through what I am going through right now and being ****med their hard earned money by big companies like MTN. All I am requesting is that my package changed to Made for me XS and pay 799 as per my contract that i signed on the 4th of June 2020 with MTN.
