ScootaMart

I bought a new scooter from this company in July 2018. As a buying incentive I was offered a wing mirror, rear scooter bag (which broke after a couple of months) and puncture proofing of the tyres. In March the rear left tyre punctured and deflated down to the wheel rim making it impossible to drive the scooter home. A kind lady saw me struggling to push the scooter home and offered her help. She pushed the scooter all the way home allowing stops for me to sit and rest on the scooter when needed. I phoned Scootamart to report the problem and waited 2 days for their service dept to return my call. Eventually the did respond and came to collect the scooter, I discussed the fact that the scooter was supposed to be 'puncture proofed' and was told puncture proofing does not quarantee that you won't get a puncture, I was under the impression that puncture proof meant proof against puncture, but hey what do I know... had I known otherwise I would have looked to buy a scooter with solid tyres to avoid the situation that occurred. In fact no puncture proofing had been carried out on the scooter which is why the tyre deflated to the rim. Scootermart took the scooter and repaired the puncture and puncture proofed all four tyres, they did try to make a nominal charge which I refused to pay given the situation I had been put in due to the puncture. Approx 6 weeks later the same tyre has deflated and I cannot use the scooter as it leans to the left which causes me pain in my back. To conclude, here I am 1 week later having phoned Scootamart 2 times to request a repair with no response, even allowing for the Easter breaks they have had 4 working days to respond. I now have no confidence either in the scooter or Scootamart and have had to buy another scooter (not from Scootamart) as I need a scooter on a daily basis. I was sold a scooter supposedly puncture proofed that left me stranded in a difficult situation surely a breach of contract? I am now left with a scooter I cannot get repaired by Scootamart as they are ignoring my calls and cannot sell until it is repaired.
Not sure what to do now!
