Bad Customer service

Hi my name is Salome, I want to complain about Old Mutual, being here with Old Mutual for almost 12 years make me sick because of the way they are handling my matter. Last month March the 2021 there wasn't enough money in my account and the Company didn't find anything and decided to visit Mabopane branch to seek advice on what to do, they gave me account details so I went to deposit the amount of R220 on the 15 March 2021 to fill that date for my policy to be in order, same month I went to Old Mutual Mabopane branch to submit proof of payment, here comes April on the 06 the Company deduct the their money 213 and 126 and again same month the Company deduct 213 and 126 on the 8 same month, then again I went to Old Mutual Mabopane branch again to lay complain about the Company deducting money twice in a month they asked my bank statement and March proof of payment they took everything and send it to head office, the lady who helped me was so professional and told me that Head office will attend the matter and did not promised me when the refund amount will be made, last week can't remember date Old Mutual paid R641 into my account and yesterday I received an sms telling me that Im in arrears for two months that o do not understand, so I am so disappointed with their service and the way they are handling my matter, o don't think I will ever refer someone I know to join Old Mutual and please do your job thoroughly before you send me an SMS, seriously I am not happy. I am sick and tired of running around to do same thing again and again and remember I am using a transport that need to be paid so pls solve my matter.
