Dissatisfied service

Bought my car on the 21st of August 2025, was happy till I had a type problem, phoned them and was advised that my tyres had a plan got the number and they told to take the car at any tyre place and they should phone them indeed took it to Supa quick they took tyres out the one had a lump that I had a problem it was replaced whilst checking others they realized that the one giving a problem is the not the one with a lump instead there was another one with the cuts inside and you can't tell by mere looking at it and was told they are not gonna replace it as it was worn out due to driving called the dealer cause I had the car for 23 days and there is no way I worn that tyre out and the dealer told me they are not going to replace because my car was taken to roadworthy test and before buying I did ask to take to roadworthy and was told I had to pay few thousands for it, ****** angry because I paid a deposit and needed to replace a type again.
