I need immediate help

My name is Nomfundo Gumede . I have a problem with capitec bank account ***. This account is locked and I found out that this account is not the same as the account in the system yet I'm the owner of it and the number i used on capitec account is not supported I don't know how and why since the number mine . This company is annoying. It's a month now my bank account been locked, I don't know the reason behind all this . I can't withdraw or transfer money but the company have a nerve to take bank charges without helping me . I went to the branch to complain about all this but they told me to bring documents such as an affidavit and a certified ID copy then told me to wait for the whole 14days . The company is really irresponsible . It's failing to offer a simple help , I'm very very disappointed with this company with its inconvenience actions.

I would really appreciate an immediate help!!!
