Cannot close RCS account

I called the call centre on 1st February 2015 to close my account. I was told that I need to email in my closure request. I did so on that day with no response, then emailed again with no response.<br> <br> I then logged a query on the RCS website, and big surprise, no response. I called again and asked to close my account telephonically but was told this isn't possible and I need to email in my request.<br> <br> My account was fully paid up when I initially requested account closure and I can only assume RCS are ignoring my closure requests and trying to rack up fees on my account.<br> <br> This poor level of service is unacceptable
