Wrong product delivered aswell as billed incorrect

Hello Cell-C.<br> On 09/10/2015 a friendly girl from Cell Direct, Meshay Ross, called me with a special offer from Cell-C for R199pm, the 20GB mifi package. I waited for more than 3 weeks for the package to be delivered. I finally got the parcel 03/11/2015 and was given the wrong router. I called Cell-C and finally after 37min explained to them my situation. The lady from Cell-C said I must now wait another 7-14 working days for them to come and recollect my parcel to exchange it, product is still sealed. She then told me, after she got a little bit tense herself, that I should either wait some more or just cancel the contract. I asked/told her to cancel it because since I can't wait any longer and since I can't exchange it myself at a Cell-C branch, I'll go get a new contract in store. 10 Min ago an amount of R185,72 got deducted. It's obviously Rica'd already by the guy from Ram couriers. I want answers as to how we will sort this out, please. Either you refund me or give me what I was promised or I'll take this further. I was promised a Huawei router and instead got a ZTE router which is alot cheaper and slower, this is false adverti*****t is it not?
