Old mutual are ******* and *****

I cancelled a retirement annuity policy i had with them in February 2019. At the time legislation only permitted you to withdraw that money if the value was under R7000. I cancelled this policy in person, at the branch.They continued to debit my account. Even when the debit returned, they just double debited me the following month. This continued until the value of the fund exceeded R7000. I had been to the branch a few times, each time the person who assisted me promised the matter would be dealt with and i would receive my refund in 21 days. Eventually i tried an online complaint submission but the lady who was assigned the case either couldn't understand english properly or just didnt really want to assist. I retried the online complaints a few times, but nobody at old mutual could understand what my issue was: i cancelled that policy before it reached R7000, but old mutual just kept debiting.legislation has now changed, where you can withdraw your money if the value is less than R15000. So i submitted the documents. A guy contacted me some time later, claiming that the bank account i had chosen for the funds to be paid into, was not recognised by old mutual. So i resubmitted proof of bank details for another account. I enquired 2 weeks later, then they claimed my id no didn't match my tax no. So i got a letter from SARS to confirm my tax no, and submitted that to old mutual. That was 2 weeks ago. Now nobody responds to my emails, the people at the branch just keep giving me excuses and passing the buck. Old Mutual are ******* and *****. As are most of their employees
