Webafrica *****s money

I have a LTE package with webafrica and signed up for a debit to deduct the monthly payment, however they have ****** two amounts out of my bank account stating the system has my profile under a credit card and just decided to take the amounts without my permission. I have been trying to get my money back from them for almost a week now and no joy. They suspend your service when you don't pay almost immediately but when you need your money from them they take their time. I'm extremely unhappy with the service and lack of customer relations.
