I purchased a list of emails for Auto Glass Shops in 3 specific states.
What I received was a list that was 90% worthless ( and I'm being kind at 90%)
More than half the listings were body shops, not auto glass shops, and of the listings that were auto glass shops, most of the emails were not valid, and many of the shops were not in the 3 state area contracted for.
I contacted them several times and they sent "improved" lists that were basically worthless
I requested a refund and they never got back to me about it.
