CANT CONTACT BUY & GET FOR THE PROMO

I bought a fridge in 2015 and with the \buy & get\" promotion should be entitled to a weekend away. Firstly, the number they provide to validate your booking is always busy and so I could never get hold of anyone. No matter when I called I was at least \"6th in the queue\". I sent an email and after resending a few times I was called by a very helpful lady and sent the documents to fill in. I returned the documents with my booking request on 23 Feb, resent on 29 Feb and to date (2 Mar) I still have not had a reply. The phone line is impossible so now I dont know whether to make my own booking or wait. If I wait too long I may not be able to get a booking myself"
