On the 28th May 2015 i upgraded my current Telkom Simple Plan (2 Mbps adsl line wiht 10 Gigs of Data for R 399.00 per month) to to next plan up also a Telkom Simple Plan ( 4 Mbps adsl line with 20 Gigs of data for R 499.00 Per month) I have a recording of the conversation with one of the Telkom agents and he said yes \Miss Bestel you will be paying R499 a month"So been over charged from 28th May 2015 to now with my line being suspended from November 2015 - January 2016 and still being billed for these month but NO SERVICE ! I have been trying to sort this issue out for the last 6 months and am having no luck. I have spoken to a number of call centre agents sometimes being on the phone for over an hour at a time. I have Spoken and been in email contact with the following team leaders : CINDY - [Email Removed] / Jody Harrison - [Email Removed] and now Tembela Ncumeza - [Email Removed] i have sent all relevant information to all of them and today my line and account is still SUSPENDED and i Have a bill of R 3589.22 as per my latest invoice on the 10th Jan 2016 still outstanding all because TELKOM cant get thier act together and sort things out.
