Retirement is a ***** with Old Mutual!

I'm trying to take early retirement and contacted Old Mutual after I turned 55. I submitted my documents during July 2020. Since then I have had a number of emails requesting further details. I have responded to the emails and made numerous calls to the Call Centre during this week. I have not yet had a call answered by the call centre and am normally cut off after about 10 minutes in the queue. Despite responding to emails from Old Mutual within a few minutes of receiving them, I have received no response from the emailed person - at least an acknowledgment from them will tell me my messages have got through.
