False advertising

Ga-rankuwa shopping centre only has one Capitec atm which has no deposit facility. Sometime last week I went there to make a deposit and had no choice but had to make a deposit inside the bank. Financial institutions always advise us to save on bank charges by using atm's to deposit. All the other banks at this shopping centre have at least 3 atm's with at least one with this functionality. I specifically moved to Capitec because less bank charges. I was charged about R275 for that one transaction.This is really not on as we have no choice. Please advise why must I stay with this particular bank? Most of the People that use this bank are Pensioners and unemployed.Can we please help them save the little that they have.This is really appauling
