Wifi Router Contract

Hello Peter, I have a serious problem with Telkom, on 2016 I app**** a Wifi router contract online (which comes with 10gig day and night for R149 a month), of which it was successful but when they brought the package, in Phalaborwa there was no network coverage for telkom at my place I didn’t use their package, I had to tell them to cancel the contract and come back to pick up their stuff. Now the problem is, since that day I told them to cancel and come collect their stuff, they haven’t canceled and nobody came to collect, every month they are deducting my money for something I am not using, I keep on going to the bank and reverse the money they are busy deducting. Last week I went to Telkom store at Mall of the North in Polokwane, I filled up a cancellation form and signed, i got a case number and they told me to wait for 30 days but to my surprise, they deducted my money again. According to Telkom i owe them R2438 for a router and a simcard/data that I’ve never used since they brought it here. They even blacklisted me because they say I owe them and I don’t because I’ve been canceling their contract since 2016 till now but they don’t cancel but take my money whenever they want. Please help. I can’t even borrow money from any bank because of what they are doing, they gave me a very bad experience, I don’t even wanna see myself getting any contract from Telkom because of their treatment!!
