Capitec fails to deliver on promises

Capitec called me at 4.45pm to tell me that their "systems have been updated" and the problem solved. No so, I tried now to email myself proof of payment, and it says "invalid email address" once again despite my email address being verified more than once. No one at customer care can help me. THIS IS BORDERING ON RIDICULOUS, YET THEY CHARGE ME BANK FEES IN EXCESS OF R220 FOR A SIMPLY SAVINGS ACCOUNT. Perhaps the banking ombudsman should be contacted next ??
