KAPSEN TYRES BAD FROM DUNLOP

I bought 4 new tyres at dunlop zone midrand on the 10th April 2019 .i used these tyres for 3 months now my car makes a funny noise when i drive which strated lately end of july and i took the car back to the workshop to understand how could these happen in a short period of time i paid a lot of money to buy these tyres and trusted your guys when they sold me these brand and said KAPSEN is a good tyres made by dunlop .so now i did not find the solution from them they said it might be the bearings of my car and .the guy who helped me was actually not willing to help me he said he has nothing to do for me with these and we tested the car with lot of his stuff there. You could see that the tyres are swelling and making a lot of noise but said he can not do anything for me ...i also went extra mile brought my other car so that they can swop tyre and check if it it what he says but nothing happend the sound kept on comming out .i drove the car for a long time capetown it is still doing the same noise but "Sean or Sham" didn't help with the problem ... i am so said now my car makes the same noice i told him about .service was not good because i couldnt get help i needed . Why do we pay lots of money and dont get help in return ? No one should go there and put in those Kapsen tyres i hate what i am going through now.also these process costed me money for those two days i spent there and get no help .
