Bad after service by Toys R Us

I am disappointed and annoyed at this common toys shop that we all support. I purchased 2 Amarok kids ride on cars as Xmas presents for my two grandsons. One of the cars did not last six months and I delayed in taking it back to the shop for repairs or otherwise as it had a warrantee of 1 year. After realizing that I need the car repaired I contacted the store to enquire where I could take the car for repairs even if I had to pay for it. After establishing that I was beyond my warrantee period they were very happy to inform me that there was nothing they could do. They do not have any outsourced repair site, and do not even even have an alternative repair centre except their warrantee, which means nothing as they cannot do anything about the cars even if it is still under warrantee as they do not have repair facilities. I am now stuck with an expensive toy that my grandson cannot use. This should serve as a warning to parents that they should not buy any of these fancy ride on cars unless they can assertain that the outlet has a facility to repair them when they have problems. Toys R Us is promoting these ride on cars, but are ducking and diving when they come across mechanical issues and hid behind their warrantees which they also duck and dive when it comes to honoring them. I challenge Tors R Us for a response, it is their duty to their customers
