paying when i shouldn't have??

I upgraded my membership to national late in December 2014 might even be early in January 2015<br> <br> and was told when i upgrade i don't pay for a month and will only pay the new fees end of Feb 2015<br> <br> However on the 31 Jan 2015 virgin did debit the money after telling me i get a month free when i did upgrade to be a national member.<br> <br> This is a mistake on virgin active side surly this could be fixed.<br> <br> I've tried to call but there is no point in trying to call, because you just end up spending hours of time wasted where no one assists you due to the fact all you hear is \Your call is important to us".<br> <br> could someone just fix this mistake please and thanks.<br> """
