We saw the add for boat rentals on KSL and called and talked to David. We had a family tripped planned to Flaming Gorge and David said he just purchased a Sea Ray open bow boat and it was available for us to rent for the weekend. He had asked for the full rental amount but I refused to pay it all up front and we agreed upon 1/2 the amount $300 deposit and the remaining $300 when we picked up the boat. We talked to David multiple times before our trip and the night before we were planning to pick up the boat; he said it was all ready to go and we could pick up after 9am. We arrived at Echo Resort boat ramp to pick up the boat and David was nowhere to be found and would not answer his calls. After several hours trying to reach David we left with no boat and were out $300 dollars and paid more money renting from the marina. David promised to pay back our money several times & came up with excuses, then stopped answering phone calls, we never recieved our money. DO NOT FROM TRUST!!!
