Extremely dissapointed

i went to the ATM and drew R800, however only R100 came out i called standard bank call centre and reported it, they told me it will be resolved by the 09/03, on the 11/03 i called back because i heard no feedback, they then told me it will be resolved on the 16/03. I still never received any feedback i called them on the 24/03 and was told by a consultant, the call is resolved and closed, i asked her how that is possible if i haven't received feedback or my money, and she apologized and said to me i should call the complaints department. For an institute that regards themselves as a 10/10 service, their services are pathetic, i have been having endless issues with Standard bank and no positive outcome what so ever. I will be closing my account with them and advise everyone i know to do the same.
