Terrible service

I have been saving with Old mutual for a couple of years and on the 25th of Jan I called them to make a withdrawal. I was advised I will get the money in 3-5 working days but I didn’t get the money on the 5th day. I called them to ask and was advised in 7 days. On the 7th day I still had to call to ask because I hadn’t received the money. This morning I woke up to a R124,97. What am I supposed to do with that? I requested for my money because I really need to use it.
