Telkom does as they please.

In my invoice this month I was billed an incorrect amount to which im supposed to pay and logged in a query and everything the call center agent told me is the exact opposite of what she said would happen. I called in again this morning to try and sort it out and the agent hung up on me. I think telkom's agent make it a habit to hang up on calls when they can't resolve a matter because its not the first time they done that to me. I regret why I signed up with telkom despite the warnings I revived form people. sometimes I think of stopping with the payments since they are refusing to help me.
