Incorrect billing and unwillingness to assist

I recently decided to give ME&you mobile a try. After 2 weeks I decided this was not for me and cancelled. Since then i have logged into there site twice to follow up and each time it shows me as still active. I further received billing for month of May and June, even though i only used it for May and cancelled at the end of May. <br> <br> Upon request for a refund this was agreed to however i was told i must e mail my card details through to them so they can refund me. Firstly they already have them as they already debited my account and secondly I do not feel comfortable in doing this as this is how card ***** occurs. I requested them to use my bank account details instead to which they refuse. I have tried on multiple occasions since to contact them however nobody answers the phones. I dont see how i am meant to sort out the issue if i can't speak to anyone .<br>
