Cannot close an account

We have been trying to close a MyMo account for many months, without success. The latest attempt is that I went to my local branch recently and they suggested I e-mail *** to try and resolve the issue. This was done on 24th March, but to date, we have not yet received a response or even an acknowledgement that the e-mail was received. Guess that is par for the course for a bank that cannot even keep its clients' data secure following the recent data breach i.e.no customer service whatsoever.
