Charge for cancelled contract and zero follow up

<p>I found out two weeks ago that I have been paying for a small top up contract, after I cancelled it three years ago.</p> <p>The contract has since been stopped but regarding the refund I have been promised (when I phone) follow up and refunds but have not even received a courtesy call to give me an update. Have Ref numbers etc and have literally been left by consultant on hold for 15min before being cut off. Shocking!</p>
