I need Customer Support Urgently

I took out a BF double deal, but have been quoted differently to what was offered. I now want this rectified or I want to cancel. But requesting the recordings takes 7 days as I'm told and Cancellations also within the 7days. So if I request a cancelation, it will take another 7 days and would block me from upgrading to a different stand alone phone device What do I do. I have in mean time requested the recordings, but my time is limited. HELP please.
