Natal Power Boats nightmare

I bought a cheap bow rider and the motor siezed after a hours use. Then I took the boat back asking for a refund. They convinced me they will replace the motor. They fitted another old yamaha 115 and the motor died on me in under 2 hours. Fuel is what they mixed and no signs or anything wrong till the motor stopped. Now after asking for my money back again ime having issues again. This is the worst thing to buy a boat to have fun with the family and getting treated like this. So sad really, just because it's a small cheap boat I mean nothing to them. I have now reported them to the Motor Industry Ombudsman and they will definitely get it sorted out. Avoid dealing with these people unless you have decent lawyers.
