My mobile moderm

They debited my account on the 29th February and from the 1st of March I was supposed to connect data but till today I'm unable. I've been calling since last week the 2nd March and even sent emails, there's no respond. Even cresta mall staff don't respond to emails not sure why. I even called the store spoke to Princess and told me the store tech is of. Today I called the call centre and was told my account is suspended by they debited and never cared to inform me why. Still on the phone I was transferred from pillar to post. 3 department's couldn't tell me why is my account suspended, I was put to hold till I hanged up and no one cared to call me back even now. Can I have my money back and this contract cancelled or must I reverse with my back.
