I need to cancel my contract as is is NOT WORKING!!!

<p>I signed a Mobile Talk contract in June 2016. The service has worked for about 20 minutes in total! In those few minutes that it actually connected, the video was distorted and unclear. </p> <p>A technician came to my house at the end of August to test the device (ref number ********** 4) , and recommended that if the device still wasn't working within 4 days, that I should request to cancel the contract as the towers were overloaded.</p> <p>Well now, this is where the problem arises.... since August I have spent hours and hours and hours and hours on the phone trying to get through to anyone to request the cancellation, but there is either no answer, the phone gets disconnected whilst I'm waiting, or if I manage to get through, I am transferred to several different people, explain my scenario, and then eventaully while I am waiting to get through to the next person, the call is once again disconnected! </p> <p> </p> <p>Will somebody please help? I would like to cancel the contract, and request a full refund. </p> <p>I am a working individual, and I have had to work back all the hours that I have spent on trying to make a simple phone call to Mobile Talk.</p> <p>Hoping to get feedback as soon as possible.</p> <p> </p> <p> </p> <p> </p>
