Unkept quadbikes and Bad customer service

Horse Riding Adventure in Cullinan: I wasn't impressed with the venue or customer service. The quad bike kept veering to the left and the handle was stiff to get it to turn right. It is dangerous. When I complained I was told to continue slow. When I refused and turned back I was told there is nothing wrong with the bike and I was benched. Money paid wasted. Others in my group their bikes kept swithing off. One stopped without fuel. For the money paid, it wasn't worth it. Also drinks do not come with the meal. So bring your own or cash because card machine don't work. I don't think the bikes are maintained properly. Our children went on those u safe unkept bikes. It is totally irresponsible of them I will not return
