      Had our ** ****** ****** *** *** into ***** ***** **** Service Department in August of 2021 for a fuel tank leak. ***** ***** **** quoted our repair at the price of $8000.00. The job consisted of The following. Removal of the engine, generator, out drive and the failed tank. The rear birth firewall had to be cut out to access the tank as well. ***** ***** **** then Sold out to Big Thunder. Spoke with ***** ***** **** concerned due to the buy out and our vessel torn down in repair. We were assured everything would be fine and our original contract would be honored. We had paid cash for the first half of the project with the amount of $4000.00 to be paid when the project was complete. Was put into contact with the Service Director of Big Thunder. Explained we had our vessel in service with *** before the buy out for a fuel tank replacement. Let Him know we were concerned due to the buy out and was inquiring on the completion date. ***** ***** **** had given us a completion in the Month of April. The Service Director stated that our tank had never been ordered and would send us a bid to complete the work on our vessel. We received the quote by email for the amount of $8000.00 which was $4000.00 higher than our agreement with ***. Contacted the Service Director regarding the additional amount. Was told that they could not honor our original agreement with ***. After several heated Conversations we finally agreed to pay the additional amount as our vessel was torn apart at their facility they acquired. We were then told that they would not work on our vessel. After months of searching for a shop, the purchase of a trailer and months of sleepless nights we found a shop to take on our vessels repairs. Big Thunder delivered our vessel to the new shop. They sent us an Email stated they had to remove our Shrink Wrap for transport. New shop informed us the motor had damage fittings. Our Vessel is now unprotected from the weather with additional repairs and cover needed.
