Poor service delivery.

Good day. I would like to inquire about the process for cancelling my business account with Standard Bank. Several weeks ago, I visited the Welkom branch to inquire about a business loan or overdraft for a business opportunity that has since fallen through, although I am currently working on reviving the deal. At the time, I provided my contact details at the assistant desk and was promised a follow-up from a consultant, which never materialized. Furthermore, I was assured that I would receive my cheque card within a few days, but I have yet to receive it or any communication from the bank. I am starting to wonder if the lack of follow-up is due to the fact that my account does not generate substantial profits for the bank. Notwithstanding the fact that I have built up a balance of around R70,000 through my business banking activities with Standard Bank, I am concerned that my credit score may have been a factor in the bank's decision not to follow up with me.
