Apple Left Me Stuck with a 10th-Gen iPad Showing Dead Pixel Issues

A dead pixel appeared on the 10th-generation Apple tablet I purchased through D&R, and I want a refund or replacement. As soon as I opened it, I registered a case with Apple, but they told me, "D&R can handle the exchange; we can't." When I call D&R, they say, "We can't do anything; contact Apple." What is the customer supposed to do, hurt themselves just to find someone to take responsibility? I told them there’s no Apple store in my city, and they sent me the number for a third-party service. When I call the service, they mock me, saying, "This is a private service." What exactly are you trying to do? Tomorrow, I will personally file complaints with the Consumer Arbitration Board against both Apple and D&R.
