******* and poor quality

What ******* from such a so called reputiable tyre company. More so with the ******* is the absolute rudness. I logged a complaint on Tiger wheel and Tyres website and no one bothered to reply or even attempt to contact me. I purchased 4 Hankook 15 inch tyres on the 22 November 2019. Left for holiday on the 1 December to Cape Town. I got back to Jhb and found a bubble on the side wall. HOW CAN A TYRE DO JUST ABOUT 4000km AND HAVE A BUBBLE ON IT???? who must now ****** pay for another new tyre??????????????
