WORST SERVICE EVER

After several promises by African Bank to re Debit orders I got the shock of my life after 2 debit orders went of this month for my credit card. one on the 23rd of May and another at month end . Please note that I have a standing debit order for the last day of the month. I spend more time on the phone trying to fix my credit rating than what I spend working for my boss. Should I start invoicing them for time and money spend or should I go and work for them full time. Might be the only way to keep my credit rating in place. What has happened to your customer service, can't complain about the service, cause there is NONE.
