Confused and angry

I received a email from telkom earlier that 11 616 has been deducted and reversed in my account cause it bounced as I don't have that money .I put a report here on hello peter a month ago complaint bout Telkom's false billing and Telkom send me and email stating that no charges will be waived from me cause of a misunderstanding at their branch stores where we talk to agents that don't explain proper information or even do their work proper I'm just so sad as I don't work anymore and can't afford to such amount but why would telkom send me mail saying I won't be charged but still get billed the same amount by end of the month which I even send a report towards to getting prove that I won't be charged explain to me what's going on Telkom
