No response from business banker for 2 weeks.

After a lengthy and frustrating process, my business was approved for a small increase on its ovedraft facility. Despite confirming that all the documents are signed and in order, we have waited 2 weeks without the new facility being loaded, I have sent numerous emails to the business banker and his supervisor, but have received no feedback, I have made numerous calls to the business banking desk to be told each time that only the business banker can assist me, and that they will send him an email. This is pathetic service from Standard Bank, which is a pity as we always received great service in the past.
