Telkom horror the saga continues bill for a service I don't have

I previously requested my line to be changed to unlimited line 20 meg line . Got a positive response from the telkom media team on Hello Peter but here comes part 2 of the Telkom horror I still did not get any unlimited line change And on my bill for the month comes the bill I get a duplicate charge 1 For my existing agreement In addition to that for a 40 meg line for which I don't have dated from the 15 of May till 30 June I my call to the accounts query dept I get told following stories I have 2 lines Which I insist I don't But they think I am gone mad The other person on the chat line Prudence tells me to call 10213 to request a downgrade . Even after insisting that I don't have the 40 meg line and that my area cannot get that line. Asked her again to check the duplicate charge standard answer call 10213
