device not working

<br> <br> My device is not working for the past three weeks, I have called in 4 times already and every time I get a consultant that says repairs will call me to set up an appointment to fix the device the following day.<br> <br> I wait like an idiot for the phone call and no one ever calls.<br> <br> I called in again yesterday to cancel the contract and spoke to Siviwe, the conclusion yesterday was that he will tell someone from Repairs to call me.I made a request to be called back on the website yesterday as well and no one called me yet again I have waited like an idiot today only to find that Siviwe cancelled my contract without my confirmation. Today Tebogo says I owe R1700 cancellation fee, I made it clear that I will not pay this amount as this was a breach of contract on your side.
