Purchased an HDTV antenna on line, after entered my zip code and they said the antenna will work in my area...it does not! It also said that if it didn’t work I could return it for a full refund, however there is no return address on anything, no phone number not even the name of the company, and as I have read in the comments I’m not the only one who got burned for fifty bucks. WHAT CAN BE DONE?
