Urgent matter that needs to be attended to ASAP!

I was debited 3 times my installment and my account was thereafter suspended. I have been to the store twice Musgrave Durban, I had no joy. When calling and liasing with the billing department I was informed that the payment was through and that the query was being attended to, I am still waiting and this had caused me much inconvenience. Beside being triple debited my account was still suspended after payment this is unacceptable!!!!
