Faulty Product

I bought a pair of AirPod Pro at the end of November. After a month of problems I took them in the first chance I got. It was checked and they replaced one of the pods. A few months later same thing. Got them back and the problem persisted. Took them in a total of 5 times since I bought them. The service center suggested I get a approval for a replacement unit. The approval was denied because it falls out of the 6 month window for replacement. The unit is 9 months old and for 3 of those months everything was in lockdown. I am also an essential work so during that time they opened I couldn’t get to the store.
