Bad service from Old Mutual

Good day, This is about Old Mutual. I have never had such shocking service from a bank as I am receiving from Old Mutual. For six weeks I have been trying to withdraw my money. Each time there is another excuse, we haven't received it, which email address did you send it to, this form hasn't been completed, that form hasn't been completed. It is now actually beyond a joke.. They advertise that everything can be done on their mobile app. Well that is definitely not the case. It is very disappointing that something so simple and that should take five days, has take six weeks and I still don't have my money. I will definitely be closing all my accounts with them
