Still billing me for cancelled services

I requested that all content services on my account be cancelled in May. I had to phone and e-mail them at least 4 times to get it cancelled and eventually they refunded me, although not the correct amount. But nobody expects them to get their maths right, hey.<br> <br> Now in July they again started charging me for content services... It is supposed to be CANCELLED...<br> <br> Really starting to wonder if they will ever get it right...
