Hell trying to close my Standard Bank Account

I have been trying to get assistance with closing my Standard Bank account. I can't go into a branch as I am overseas. The person who I have signed power of attorney over to assist with this has been given the run around. I have been calling, leaving messages and sending emails to the private bankers and have had no response. I refuse to transfer any more money for fees into this account due to the lack of human respect or even a courtesy mail or call back. In one night this week the calls cost my R500 to standard bank with no response. This is absolutely ridiculous!!!!!!! The staff that refuse to help me close my account can happily pay the fees on this account. It took my husband one phone call to First National Bank and they closed his accounts??????
