no service - no feedback

On the 4th of May (5 weeks ago) I ordered a petrol/garage card . Discussed by telephone. The documentation was send via email, and waiting time was 5-7 working days. On the 12th I inquired about the card online – no response. Promised feedback within 2 days. Nothing was yet done On the 19th of May I received an email to fill in the mandate for our pastor. This mandate was send on the 21st of May. Still no feedback from FNB. I phoned again on the 26th of May – still nothing was done. And I am still waiting… Your 5-7 days is a myth I find this type of service unacceptable, because there is no service
