Dollar General complaint: FALSE ADVERTISTMENT

I went to all locations of the Dollar General Stores in the Calhoun, Ga and surrounding areas looking for a DEEP TISSUE MASSAGER that was on sale for 1 DAY ONLY – 1125 from 7am to 10pm. For 50% off the original price.
After being told multiple times that they didn’t have this product or they did but didn’t have the time to put out NEW stock because they were understaffed. But still wouldn’t look and see if they actually had the product that I was looking for. Even gave my number to several stores and never received a call back from none of them and then I called several stores and they told me that they didn’t have the product.
Which I have placed calls before and asked about a product and been told they didn’t have it and then go to that store and it was actually there on the shelf someone just didn’t want to go look for it.
I am very FRUSTRATED this was a gift for my parents for Christmas.
As a company you need to list locations or something to keep people from running all over and wasting gas (AS HIGH IS GAS IS NOW) trying to find a product.
And this week it has been offerred for $30.00 and still NO PRODUCT in the stores.
