no free gift

i have been a loyal Home choice customer for the past few months but i was disappointed when i received an incomplete order. it was a buy one get one free sale and i ordered the Gina towel set. to my surprise, when i received it there was no free gift. i then contacted Home choice and was told that it was while stocks last and that if i did not receive the free towels it therefore meant that they were out of stock. surprisingly in the pamphlet, there is no where stated that it is while stock lasts. i feel that Home choice is misleading their customers, i mean why advertise such an offer and not deliver on your promise.
