Capitec Bank system failed me

Capitec still did not resolved my one and half query. They told me on this platform that the query was assigned to someone and will I will receive a call from them, till today nothing has happened. My question is why are they starting a system which they fail to honour and fails clients. Capitec bank don't deserve any rating, they are incompentent and useless. If not clients complaining about their lost monies from their accounts, it is their poor service.
