Cancellation of contract taking over 1 year to resolve

<p>For over a year we have been billed for a contract that we have not been using. First request sent with all supporting documents on the 7th of October 2015! We finally got some sort of help on the 19th of September 2016from a lady called Letchie. Yesterday; we recieved a bill again; and was now told by Letchie that she cannot assist and we should phone the call centre.</p> <p>How many people do we still need to speak to???? Is there someone with ANY knowledge that can please get into contact and resolve this matter? </p> <p>Samantha - ********** 955 OBO DR Petrarolo</p>
