Ceat Tyres — Irresponsible answer from the dealer I bought

Address:

Madurai

I purchased a tubeless two wheeler rear tyre from Jose Tyres, Tirupparankundram, Madurai for my Activa 4G on 17/7/2019 fitted by their mechanic only. I hardly used my bike for a lesser time as from March 2020 it was covid 19 lockdown. But I found my two wheeler rear tyre rubbing one side in whole periphery. I checked with some of the tyre mechanics they said this hardly happens with two wheeler better change it otherwise very sooner it will burst. I went to the dealer with the bill but there are not giving proper answer and not even checked my bike tyre. I am very upset regarding this and told them I will complaint to ceat tyres but they said go to court also there is no problem. Kindly you cest tyres give me a answer.
I herewith attached some photos of the damaged tyre and the dealer bill.
Thank you,
