After service

Hi took out an adsl line in lockdown it was supposed to cost R199 for 6 months and then R300 there after for 18 months I never payed R199 i spoke to the sales agent and he said i need to go to the n1 city branch for answers. I went yesterday and Ilaam Safodien told me they don't deal with inquiries or billing and she can't see what I paid last month or what I need to pay to make the contract paid up just the amount I must pay and that I must pay at checkers they only deal with new business and with attitude said go online and sort it out there I when ask the sales agent what to do and he said they must help me at that branch so what do I do I'm being send from pillar to post there is no after service from telkom is this the level of service telkom prides itself in.
