Cancelled domain and still being billed

I had 2 domains with mweb when I originally signed up with them for hosting. In August 2013 I sent an email requesting cancellation of the one domain and got a reply to say it would be cancelled. It wasn't cancelled and again on 13 November 2013, sent another email requesting cancellation, and received the same reply. <br> <br> Now 2 years down the line, the account is still not cancelled and mweb refuses to pass a credit dispite me sending them the original cancellation requests. <br> <br> When I phoned in yesterday (17 March 2015), they advised that the domain was cancelled, but still proceeded to send me an invoice billing me for thew domain that was supposedly cancelled!! <br> MWEB is useless, there is absolutely zero customer service and I am still sitting with a domain I dont need and they have proceeded to take the money every month for the last 3 years.<br> <br> I just want my refund and the whole account closed. I will continue on social media until this issue is resolved!!!
