Lombard tyres disgusting

a minute ago New I will never buy here again bought a new tyre end of February a week later a flat tyre took it back I said no problem I will pay for a new tyre now not even a week later a bubble appears on the new tyre and I get told no you hit a pot hole. I don't know who can afford a new tyre every single month but I I know I can't. And disgusting service when I shouted at the one in charge I was told he is going to put the phone down. He refused to even listen just sorry pothole damage. Never will I use Lombard tyres again.
