BUY1 GET 1 FREE MISLEADING

HC advertised the towel sets and Michelle duvet as sale items that if you buy 1 you get 1 free. I paid four 5 piece towels and two 9 piece towel sets and a Michelle double duvet set. In total l was supposed to receive 12 towel sets and 2 duvet sets. But l have not received any of the free gift sets. I have followed this up and l am told its out of stock and now instead of 9 piece sets l get either a 2 piece (in lilac)or 5 piece set (only available in brown). The Michelle duvet set l paid for a double and now they can only give me a 3/4. I have queried this and l was told there is nothing they can do and this is not the first time this has happened and I am not the only person they have done this to. Now why do they advertise and mislead customers and then throw their hands in the air when they can't supply what you have paid for. It is unfair that l have to have a company that claims to be the best online shop and yet treats customers like ***. Who ever is responsible for stock control is failing to keep stock of what is available and make sure that people get what they have paid for
