Disgusted with Capitec Bank

Sunday 20 October I was busy depositing money +-R3000 at the Glengarry atm. The atm switched off in the middle of my transaction. Now I am being told by the bank they only see an unallocated amount R1200 and not +-R3000. I am told by the horrible consultant who called me this morning, that I can take it or they close the case, and I get nothing? What the hell? Why am I being held hostage over my own money. The only reason I said +- R3000 was because that the amount I had in my purse but I did not count it again before I put it in the atm. So Capitec wants to just keep my R1800? Your consultant was disgusting on Sunday and this morning when she called me again, there was no improvement. I moved all my banking to Capitec and have been very happy so far... until Sunday. And no effort is being made by a manager to call me back. I have been waiting for 5 hours. I called again and after 10 mins on hold, I was told they cant find a manager on the flooor. OMW!!!!!!!!!!!!!!!!!!!!!!!
