Bad service from Old Mutual call centre.

My father passed away on the 30th December 2020 and we were not aware he was owing SARS as he was not someone talking to us about his finances. So I had to do his tax returns from 2014 till 2020 and all others went through besides 2014. So I phoned SARS and they told me they were looking for a Tax Directive 2014 for a lump sump that he got paid for his disability claim. I sent an email on the 1st February 2021 to *** requesting a Tax Directive and there was no response. I called the call center on the 15th of February and the last call was on the 6th of April but still nothing. If count logs of the calls that I have made they are 22 and these calls average up to 20 mins per call. My mother went to different branches of Old Mutual in King Williams Town and Bisho in the Eastern Cape but nothing yield good results none of the people in these branches knows what is a Tax Directive. I'm not writing this review to paint Old Mutual as bad but I need it's been two months waiting for this review or even feedback.
