just go back to them, make them take these tyres back, sell it back for slightly less, but recover 7-80% of the amount....
I went to buy bike tyres last year, near lahore railway station. The guy claimed to have German tyres, they looked good, but sidewalls were scraped with a blade.
I talked with a good friend on phone, who advised me to recheck, k choona naa lag ra ho.
Sure enough, i spotted half cut star of servis logo.
Then i searched the name "cruiser" on google and lou gi, it was servis tyre, made in pakistan, and it was a B grade tyre, which is rejected from factory.
The conclusion is, everyone out there, wants to skin you alive
take some friends with you, this is not a case of you, changing your mind. This is a case of fraud, you were told that these are 2018 tyres, which are in reality 2010 tyres...
