Very bad experience ever..poor service and unprofessional

I settled my account last month, sent proof of payment and requested them to provide me with a paid up letter and close my account, I have not received any response.

I have attempted to contact them multiple times, phone rings unanswered. Today my account was debited again. I have since sent an email and message, yet I still have not received a response. I want my money back. They are quick to approve application but are hard to reach when customers need help. Refund please
