LACK OF KNOWLEDGE

I have 3 Contracts with cell c, the other one is due for an upgrade i then phoned them in April to tell them to cancel it, they sent me a massage saying it was successfully cancelled. Then in May they sent me a massage saying my account is in arrears and they will suspend it, which they did. When i phone them to ask why is it suspended no one of the consultants is telling me a valid story, they keep on transferring me to different departments until they hang up.
