my sister rang Sky last week and asked for a price including installation for 2 Sky+ boxes. She was advised by their sales dept. that they had an offer on at the moment and the price would be £30.00 all inclusive. My sister queried this several times during the telecon and even put the phone on loudspeak so my Dad could here the sales rep. and each time the offer was confirmed 2 new Sky+ boxes including installation for a TOTAL Price of £30.00. Yesterday she received a letter confirming 2 plus boxes at a price of NIL and installation @ £30.00. The engineer arrived today and said they were only supposed to be installing only 1 box. I rang Sky on her behalf and eventually was told by a Team Leader that the sales rep. that took the order (and payment) had made a mistake and the offer was for 1 Sky+ box and an additional card for another box. As the original sales rep. took the £30.00 payment at the time of ordering and as my sister queried what was included in the deal several times during the conversation have Sky formed a contract and are they legally bound to supply 2 boxes or not.
Sorry a bit long winded but hopefully you get the picture. Hope you can advise.
