false advertising

Thet advertised some great black friday deals, but had only a handful of a few of the items advertised. example they only had 5 units of the toilet set advertised. And on their ad they did not specify the quantity of speacials they advertised. Most places state the quantity of the advertised product availbale, so you know your chances of getting the product This is totally wrong, and the attitude of the sales person or manager was of the i couldn't care less attitude.
