UNACCEPTABLE "PRIVATE BANKER" SERVICE

I have been a Private Bank client for many years. Although I pay the monthly costs, I seldom use this service. But the day that I do need assistance, I certainly expect to receive same. The last Private Banker responsible for my account was one of the longer remaining Private Bankers I had since becoming a Private Bank client. Usually when there is a change, I receive a courtesy, introduction call from the new Private Banker. This time though it did not happen. I emailed the Private Banker I was assigned to and received an automated reply that he has left Absa's service and the new Private Banker's name and email address were provided. I emailed the new Private Banker requesting information and did not even receive an acknowledgement of receipt. I tried to call in vain. Since Monday this week I tried to speak with his Supervisor to no avail. The message was passed on to him but seemingly not even he thinks I am worth being a client …. even tried his cell nr but had to leave a message. Shall I change banks????
