Hello all, I ordered 4 new tyres from an online retailer at the beginning of April 2018. Right after the assembly it was noticed that all 4 tyres have a height impact. I drove about 100km, because I thought that tyres were wrongly balanced. The online retailer had all the tyres picked up and after only more than 5! months there is still no decision. I announced with deadline that I would undo the purchase. The dealer does not respond to this. Do you have tips on what I can/can? VG, Andy
