Absolutely appalling service!!!!!!

I was informed I need to submit my bank details for an Old Mutual claim last week. The banking details were submitted on the 21st of August 2020. No acknowledgement was made by Old Mutual. I call their useless call centre each and everyday, and after holding for thirty minutes the call hangs. This is not by my doing. This has happened multiple times with your call centre consultants deliberately hanging up calls. Old Mutual is not giving me any feedback, and not only that but they are completely unreachable. I am appalled by this level of service especially considering the sensitivity and delicacy you should be treating grieving people with.
