Old Mutual is providing poor services in responding to death claims

Good day I would like to share my frustration with the lack of support and inconsistent service I have recieved ever since my father passed away on 15 July 2020. The office I consulted is old mutual Mams Mall. They indicated that I needed to bring the necessary documents. Then I went to gather all the information and since then I went to Silverton Branch..they could not help me..I then proceeded to tshwane mall branch..they also could help me and tell me a definite information or even assist me. I went to Brooklyn mall again with all documents still the person who was helping us seemed unsure of what they were doing. Every branch I went to they scanned all my documents which included my father ID, death certificate, letter of excecutorship, my ID and my 2 siblings ID . Our bank statements. So you can imagine this repeated activityty was annoying. But I comp**** with all the branches On 27 July recieved a call from old mutual that I must submit all the required documents. I did a they did not respond or acknowledge receipt of document.. ever since I have been recieving messages from old mutual that I must submit documents. to date I have a trail of emails that I sent to them with the reference number. But still they are still asking me one and the information repeatedly. I'm very frustrated and appauled by the lack of response from old mutual. Their service is very poor and inconsistent
