Nationwide Window review: Beware 1

Dear Fellows, Beware of Nationwide and Siding company. Company sales person are very dishonest person. Earlier I got quote of $22, 000 for Window and Siding job. I say NO THANKS as price was too high. They negotiated on phone for $18, 000 . I again say NO THANKs. I told them I will get more quotes from other vendor and after that I will decide if I wanted to go with Nationwide. After few days I contacted sales person on phone and asked if the old price of $18, 000 was valid if I wanted to do Window and Siding job and he said yes. He can to my home and gave me new quote which was $25, 000. When asked what happen to $18, 000 he said the $18, 000 was only for Siding. I was so surprised and never called him back. But he started sending me nasting emails with improper words and sending in email racial abuse. I was so starled with this behaviour and reputation of company. Also he suggested that he can do job in less money but outside of Nationwide. So he is also not honest to his company. Beware of this guy and do not allow him in your house and BEWARE OF NATION WIDE WIDOW AND SIDING. They can change their quote anything and will try to screw you.
