No Contract / No service for 6 months

Frustration cannot even decribe how I feel about Cell C!! A few months ago I made an enquiry with Cell C and Telkom regarding their wifi contracts. A Cell C agent contacted me and after discussing the different packages that they offered, I advised the agent that I first want to get more qoutes from other networks. The following week I received a courier package with TWO wifi routers in. I then returned it after the weekend, still sealed and unopened in the original packaging. The following month the debit order went off my bank account. Take note that I did not agree to any contract. I did not sign any documents / contract Nor did I activate anything. I then returned the debit o4der and contacted Cell C whereby they advise they will cancel the contract. To my despair, I now realised that I am R801 in arrears for some5hing that I did not sign up for. Therefor I am unable to continue with my student loan for this coming year because Cell C is under bad debt on my name. After several attempts to phone them, email them and visits at the Cell C Klerksdorp branch - my complaint is still not sorted. I hereby request Cell C to cancel the contract and to provide me with a written letter that I have no obligations further with them.
