Atm deposit

Their service is pathetic and poor,fnd greenstone branch. We deposited money on Monday at the atm and I was with the sarff member then the machine took the money and immediately the machine/atm went off. Then the slip came out saying the money was not credited. Then the staff member promised us that the money will be credited back to the account after 48hours.Then after those hours the money is still not credited. My father went to the branch on Wednesday and the consultant told her that it will be in on Thursday Then Thursday still the money is not there even now. Please help.
