DISGUSTED BY THE SERVICE RECIEVED

I am in absolute shock with the horrid service I have recieved. I have taken out a contract with wasn't delivered for a month and with zero communication. My order apparently got cancelled (not by me) and recaptured with a new order I never agreed to. When my order arrived I called today say my order is incorrect they said the one I ordered is a special that is at an end. Who gave them a right to decide what device or deal I want with no concent. I have recieved not a single call from them I have made countless calls to them to be told that there is nothing they can do but open a case and it is my problem. With the case I got 1 sms which was no help at all. I am expected to pay for this device at the end of the month that I DID NOT AGREE TO AND NO ONE WILL HELP ME. The device I recieved is also faulty but because they did not recieve my query which I did send even went into stores and called multiple times. Got told my time has lapsed to return the device but I continue to explain that I did send through a query got told again it's my problem *ATTERLY DISGUSTED AT THIS PLACE* MTN SHOULD BE ASHAMED THEY ARE IN BUSINESS WITH THESE PEOPLE.
