Incorrect Billing for device which was not used and after courier collected the device they made use of the sim card

In November 2017, I app**** for the Huawei mobile wifi router which was on special for R99. The sales consultant selected the incorrect wifi router applying for me, for the B315 wireless router SmartBroadband Wireless 10GB. My friend and I had app**** for the same wifi router so when she recieved hers she sent me a picture telling me that they had given me the incorrect contract. The same day, I called the call center to explain that I had been given the incorrect contract, they told me I should contact 10213 telkom sales which I did the following day because they had already closed. I called them and explained to them the situation. They said they will cancel the contract I had and redo the order for the R99 deal. They also said they will organise with Courier it for pick up. This was end of November 2017, I waited the whole of december 2017 and no one came to collect the router. I also did not use the router because it was not the order I wanted.Telkom begining of January sends me a bill for the router amounting to R 775.48 for subsription fees x2 making R100, for SmartBroadband Wireless10GB x 2 making R675.48 and for Deal Wireless Activation Fee R200 they add it and subtracted it calling it a discount. On my statement it shows no usage for the entire period it was in my possesion. I called 10213 again and they told me they will sort it out, I should send them my bill so they can send it to billing to cancel it and also they arranged with Courier it to come collect the device. I comp**** with their requests and I sent them the bill and I handed the router in its original packaging and also with the sim card in the box. I enclosed the package back into the Courier it plastic and sellotapped it closed. I thought the issue will be resolved, and contract cancelled but nothing was done. I called a few days before the end of January 2018 to enquire weather the bill had been cancelled. They said no, nothing was done and to make things worse from the 9th of January 2018 there was usage on the sim card. The bill for the usage is making R 1,311.78. They said they will open a case for it and try to fix the billing error. The end of January I reveresed the debit order and I went and paid to Telkom the amount I was owing for my current cellphone number R249, using the reference number they gave me. Yesterday 2018-02-14, I recieved an sms from Telkom telling me if I do not pay R1954.31 within 48 hours they will suspended the service on my current cellphone number. I sent Telkom the proof of the receipt the courier it guy gave me when he came to pick up the device it is cleraly showing the date January the 8th.Telkom was unable to follow up on their own oders to make sure the device was recieved by them from courier it, so they can suspend the service for the sim card that was ****** by Courier it people but they are going to suspend the only number I have to communicate. I have listed this number everywhere so I need my number.I requested to talk to the team manger and I spoke to Paul Maphoto, all he could say was his sorry for the inconvience but the services will be disconnected on my current number he said the issue has been escelated, they have sent the matter to concellation and they will try to fix this issue by the end of next week. Telkom has been aware of this probelm for the end of January nothing has been done. They gave me this case number ********** 6, which is useless to me because the matter is never resloved. Everytime its been sent to cancellation, but nothing is ever cancelled. Telkom Managers MY CELLPHONE NUMBER WILL BE CANCELLED WITHIN 48 HOUR BECAUSE YOU FAILDED TO HELP ME. I have been a loyal customer for many years and today all they can do is say how sorry they are for the inconvience and wellingly send me cancellation forms becuse i am failing to understand how they cant help me. Its a very,very,very big inconvience, and they cannot even offer me with another solution or alternative wihile they fix this matter. The service at Telkom is extreamly bad and I am very dissapointed with Telkom for not been able to assit me with this issue.
