My dad signed a contract for water heater at the door in January 8th 2018 and today I got a bill for tankless water heater. The saleperson said the amount for monthly payment will be covered by a credit which is not true. He claimed the water heater is old and if anything happened to the reliance old water heater they will not able to fix it. He want to find a reason to sign an expensive long term contract. The old water heater was working fine and we are only paying 20 dollars a month. Door to door sales are illegal since March 1st. I believe some companies are not abiding by door to door sales ban and forging signatures.
