Terrible Admin/System Costing Their Clients Money

I paid using my credit card and their online payment portal, yet somehow they are not able to allocate the credit to my account, and suspended my service. Ended up paying again just to have it switched back on, with the hopes that they would be able to sort out their issues, yet a month has passed and they still haven't allocated my credits but they have suspended my service again.

Pamela from their support department has been helpful but I've been waiting a month for her managers to get into contact with me.
