VERY BAD-Bad Service Capitec Bank

My name is Mrs.CC Mdaka : acc no: *** i would like to report bad service received from Capitec Bank. I deposited money into a Capitec account using a contact number and apparently the Capitec number is linked to 2 customers at Capitec bank and the person i was depositing did not get the money. I called Capitec call Centre to assist they tell me there is nothing they can do to assist. the number reflected the correct details as the number i have. what kind of a Financial Institution tells me there is nothing they can do the money have been used by the incorrect receiver. They didn't even bother to check.
