Old Mutual should not be in business

My dad passed away in Jan 2025 and he had an investment with old mutual, with my mother being the beneficiary. after he passed we went to the branch to lodge a claim, the consultants at the branch did all the wrong things from completing the wrong forms, not completing vital information to missing information on the form. This was on going from Jan to April of us going in to complete a section that was not ticked. and mind you old mutual was not calling us, we would find out after making a follow up each time. I eventually logged a complaint and was advised that the payout would take 5-7 days, today is day nr 16 and no feedback on my follow ups has been responded to. From January to May we still dont have a way forward with old mutual. I have opted to log a complaint with the ombudsman. Worst service from customer facing people to the back office.
