No Customer Service

My account has been blocked for the third time in one year without a notice from the bank. I take off from work to go to the nearest branch who is Tyger Manor, to update my information. They dont even bother to update it. Few months later it is being blocked again without notice, go to Tyger Manor they put the information incorrect on the system. A week later the account is still being blocked. Call Centre dont want to assist I must go to the branch. I send emails to the branch because I cant get off from work again, they don't even bother answer my emails.<br> What must I do to get customer service from them.
