I schedule a appointment with josh cohens for a estimate on my furniture delivery. They send me one estimate which 1150.00 and that was the amount before Joshue arriving for my final estimate. Finally Joshue came on January 30 with a final estimate of 1450.00. The. Loading date was February 5 they came and loaded my stuff then when my husband went to sign. The price was now 2350.00 close to 900 that we did not agree and that wasn't the estimate we had a written contract for. Wheny husband said take everything off the truck. The guys said no. And he was going to also take our deposit. So we had to leave half of our stuff behind and he still was changing the amounts every 5 minutes. So I need help on getting my furniture plus for the money I legal sign for to pay.
