no assistance from contiSA

i have purchased 2 continental contact sport tires in November 2020 and i paid almost 7000 for those two tires due to Covid and working from home i hardly used my car. to my surprise a week ago i took my vehicle to a tire shop as i picked up a nail on my back tire and they inspected the front tire and it already started to ware and i hardly use my vehicle and in the 2 years of having the tires i must have only done about 7100kms. i contacted tiger wheel and tire in ballito who asked me to speak to the rep which i did i sent him pictures and the wheel alignment report without even inspecting the tire the tire they said theres nothing they can do to help, im guessing they "assumed " that because i drive a high performance car i must have damaged the tires but i have advised them to come inspect my back tires on my car which was previously on the front and i changed it when i purchased the new tires, the tires at the back has way more life then the ones i replaced new and they must be over 5 years old further to that I'm not an idiot to damage tires that i just spent 7k on and in addition to that i have 2 young children. please assist me in this regard as I'm absolutely unsatisfied and i would not recommend anyone to purchase tires like this.
