Terrible Client Relations

On the 26th of August 2020 I got in contact with Old Mutual because when I was doing my efiling with SARS I discovered that Old Mutual filed an IRP5 which was already reconciled for 2019 again for 2020. The only way that this problem can be resolved is for Old Mutual to remove this IRP5 from my profile at SARS so that my efiling can be processed. The only person that has assisted me at the company is Nelisa Ndleleni who would email the relevant people that have the power to fix this and she would no responses. She is the only one that responded to my emails, or even picked up the phone to get clarity on certain issues. Why should I have to suffer for this mistake made by Old Mutual ??? 6 weeks of waiting and zero response or assistance ?? I am very diagusted.
