Bill still not fixed and line down

I have received a bill to the amount of R2819.8 as charges for March carried through from January and February for an ADSL line. I cancelled this service in DECEMBER 2014 already and it was a mistake from Telkom to cancel the services LATER then agreed. My account was 100% paid and cleared at the time of cancelling this service!?? I do have a reference number for the cancellation: A***6 <br> <br> I have sent COUNTLESS emails and have been to the store without any success! What is going on?? Why can they not sort this out? I am not paying for something I cancelled a long time ago! <br> <br> Now my Telkom line is cut and I need it to do business from home. I do not mind paying for the line, but not for the ADSL service. <br> <br> I am VERY upset about the service received from Telkom!<br> <br> Please follow up ASAP!
