Below poor service

I got deployed out of the country in June to Mozambique , I therefore suspended my services. Today on this Saturday afternoon I called supersonic to re connect me and I was told I needed to pay an amount due from June to August. How is it that you credit someone for services not provided? I'm told I need to pay over R1000 I arrears which accumulated while my services were down. The consultants aren't even able to view data usage to determine if I have been connected and using the services in the last 3 months, they are just fronts who don't have any access to the platforms which clients so dearly need. All they can say in every attempt I made is that, " wel escalate it"
