Bad and no service from Standard Bank Business

I have a business account at Standard Bank. I've sold my business and now I need to close my Business Account. I've went to my branch where I've opened the Business Account. The Branch Maager was very rude and said I can't close my aco**** at the Gardens Cape Town Brance - I need to go to Long Street. I've explained my situation to him. He offered to send the Long Street branch an email in order to phone me and set up a meeting at Gardens Centre Branch. (That was almost 3 weeks ago) Up to now I still haven't received a call form Standard Bank

I've logged 4 additional queries via their call center.... still no feedback

Today I phoned the call centre again and asked if I could please speak to someone at the Long Street Branch. I had 3 failed attempts. No one at Long Street even answered their phones.

I owe R 155 as monthly fees on my business acc due to the slack and bad service from Standard Bank.

Please can someone just get back to me as I need to close my bank account before the end of the month as I will not be held liable for any bank fees.
