Pronto Plumbing Heating Air Drains

We called Pronto to assess our water heater in January. The technician, Jesse West, came out to our house on January 11 and told us we would need a new one. He showed me the figures for one with a tank - about $6300, and a tankless one - about $7400. Jesse told me I could receive a rebate for the tankless water heater from the gas company. I asked how much and was told about $1400. I said that the tankless water heater would actually cost us less than one with a tank. My husband came into the room and I repeated what Jesse said and he responded in like fashion that we would actually end up spending less for the tankless one.
Flash forward four weeks and I received a check for $400 not $1400. I called in to complain and had to repeatedly call to get a response from Jesse's manager, Bobby. When Bobby called I repeated the events surrounding choosing the water heater and he said it was all heresay and there was nothing he was willing to do. I told him he should teach his workers not to tell customers the amount of the rebate and that they should tell customers to research it for themselves before making a decision. He just kept repeating that there was nothing in writing and that I could always get a tax break next year for installing a high efficiency water heater. I repeated that he should tell his men not to tell people the rebate amount. He insisted that some gas companies gave as much as $1400, which is a lie because according to the pa.gov site rebates range from$250 - $500. He then basically called me a LIAR for stating that Jesse told me $1400 because he, Bobby, wasn't present for the conversation. That was the last straw. Remember to get everything in writing with these companies because they will lie to you to get your business.
