Lows glass, and their customer care is legendary, it is hard to get such good and personal service these days anywhere, even at home : )Stanley Antonides, Who ever he is in the company, is one of the finest gentlemen I have had to deal with. He never forgets a face or an issue and always takes outstanding and excellent care of his customers. The job does not have to be a 1000 dollars or a 10 dollar one. The time he takes to resolve an issue is outstanding and refreshing... Thank you.
