Force1 “H102 Velocity” High Speed Remote Control Boat

What a nice little r/c boat I thought. That was until we ran it. So I bought this early for my son's birthday this month, June 15, of 2018. Bought in March and have had it stored away. Took it out on Thursday June 7 and thought I'd give it to him early as we took a camping trip from the 8- the 10th. I opened it and charged it up while I went through the instruction manual. I greased it and all as book didn't say if it came like so from factory. Seemed like it had some but went ahead and put some more. We setup our camping spot and hit the lake for some sight seeing and so that I may surprise him with his gift. He loved it. We put it in the water and ran like a champ. It's great, battery died and upon taking the battery out I noticed the motor was really hot,(it even has a "don't touch" symbol on it. So we relaxed and let it cool down before putting in the other battery and having another go. So we did just that, it "died" rather quickly; more like the motor burned out. Or so I thought, or I didn't charge the battery fully. I opened it up and indeed it was smoking and there was a charred surface around beneath the battery. Utterly dissapinted! We all were. That was on friday, our first day and 2nd use out of it. ARE YOU SERIOUS!!!! Says it has a water cooling system, yet there is no actual pump to pull water from whatever body of water you're running it in. Got home today, and disassembled it. Put it back together and gave it another go. Runs slow as in limp mode and battery died within a couple seconds. UTTERLY DISSAPOINTMENT!!! $70 down the drain. I can't even return it because the window closed in April. Ridiculous! I should NOT have to look into repairing it! How can I even get a refund or an exchange for a new one!!!!???!?!?!?! NOT HAPPY AT ALL!! I had to wait until it was in stock and went ahead and ordered it as I didn't know if I would order it this month let's say, they would have it in stock or not. What do I do in this situation. I'd like to make a claim for a faulty product!!
