I want out!!!

We took a new contract and before it was delivered we changed the deal,confirmation was given that the change was done and delivery would be within 5days.We were also told that we could check the availability of WiFi in our area and if it is not to our expectations then we can cancel within 7days.Now we received the package,activated it and found we have the incorrect package,wevalso discovered that there are no hotspots in our area,so having this contract is houseful useful to my family,we asked for help with the text online service but no luck,we sent multiple emails and no one can even call or acknowledge receipt of the mail.I am fed up,can Telkom please come get their stuff and get me out of this contract I cannot bear this horrible service for 2years.
