Reversal

Good evening On the 03/10/2018 I made withdrawal at San Marco centre in Ladysmith using a Standard bank atm. My limit was changed to 10k and I withdrew 5k. Only a slip was given with technical error and no money. I then tried again and same result! By then 10k went off my account and a notification came to my mobile. I then rushed to old mutual in Queen Street and layer the complaint. They made me fill in 2 dispute forms and submitted it. A reversal of 5k was done an up today I am still waiting for my 5k balance. I have been contacting money account and they have said the case is escalated. I have been going into the old mutual branch and they have been doing follow ups aswel. Yesterday I called money account and they said they awaiting Bidvest to do the reversal! Today I called Bidvest customer care and explained my case and was told they don't deal with clients I have to get the bank to call them. Why is this taking so long to do my balance reversal when the 1first reversal of 5k was done within a day and now my balance of 5k is taking almost a damn month! #annoyed.
