Unhappy tiger wheel Durban branch in town

I have bought bought new tyres for my vehicle in august but the quality of the tyres is so poor it easily get punched on the road and I am only using freeways to travel to work however I have been punched more 7times and I did report the matter by tiger wheels where i actually bought the tyres I paid R8200 for 4 brand new tyres and I am highly disappointed with the treatment I have received from the manager of the store today when i tried contacting them because I did contact them more than 2 times complaining about the same thing but they never get back to me and today i requested to speak to a manager and he said what he must if I am the one picking the nails on the road I am so disappointed with the poor quality of the tyres and the rudeness i received from a male called a manager in Durban branch tiger wheels..I am so seeking for your assistance as these tyres are meant to be brand new but the quality is just not good at all and no one has ever contacted me since..
