We got countertops and sink from Granite Trans.. Sink cracked in 4 years. We( the consumer) had to go through the sink company which is located in New Jersey to get new one. Granite Transformation said they had to install the new sink because if something were to happen to countertops the warranty would not be good. Cost $350. New sink had crack, this is after GT guys tore out old sink. So we sat with no sink at all. Again we contact sink maker, it is on back order. Long story short...GT found us a sink in Omaha and they had an opening for next day to install( it was a miracle!) Installed on a Wed. got bill on Friday. Phone call on Monday wondering when they can expect payment. Customer service not a strong point! J.F. read more
