Dysfunctional services and poor customer service

When I try to transfer money from one of my accounts to another using online banking, I receive an error message saying that I am not permitted to debit my account. I am currently out of the country, so am unable to call the customer service line to receive assistance without incurring large costs. As a result, I submitted a query using the online contact form. After receiving no response for three days, I submitted a further query. In both queries I noted that I am abroad and am unable to call the customer service line. Eventually I received a response advising me that in order to receive assistance I should call the customer service line. So not only am I being denied access to my own money, but the customer service are completely ignoring my plea to get assistance without having to make a very expensive phone call in order to do so. No wonder South African banks have such a terrible reputation.
