I'm so disappointed and loosing trust with standard bank.

Standard Bank - South Africa I'm loosing trust on standard bank each and everytime, I last used my standard bank student achiever account in 2018 January, because my bank card expired, so I stopped using the account so now the bank charges have accumulated to R6500 over this period of 3years and I was not using the account and no one bothered to call or send sms to make me aware that if I am not using the account the bank charges are increasing with an interest, they just watched my bank charges debt accumulate.
