Apple India — Unprofessional ASP and Customer care

Wonder if there is an escalation method to Apple HQ. My experience has been terrible at ASP Service provider. I recently went twice and have deposited my iphone 16 pro. ASP prepared erroneous reports. Wasted my first one hour, while this senior citizen was standing at his counter, and he sat. After 90 minutes standing, my Iph16 pro got accepted. Prior to this, I had shown my phone to same ASP. He already had tested in my first visit. Since first report was unclear to me, I called apple escalation team, I believe they operate from Ireland. They guided me to deposit phone for repairs. They suggested to plan 15-20 minutes for acceptance at Unicorn MG road, Pune. I reached ASP Unicorn on time. After re-checks and acceptance I was told I need pay 16000 INR (200 USD) now or later, for backglass change. Back surface cracks appeared after accidental slip, of one foot, from pocket while gardening in US. Phone was bought at Burlingame Apple, CA, mid October. I chose to pay later, to the ASP. ASP, and also Ireland earlier assured me the front camera stop and screen dot, both issues which had appeared three weeks after fall, will get covered in Warranty. But ASP later called me and sought additional INR 36, 000 (app 425 usd) for new screen. He agreed, while no external dent seen, but saw "internal dent", on other side. Wonder how internally a phone dents, on another side without external dent. The fall, only drove the bottom edge back glass surface cracks. Same assurance (200 usd only) by first lady who spoke from Apple Customer Care. Black screen dot only appeared 3 weeks later as also front camera stopped. Externally, no dent on phone can be seen. No other fall either. Phone is still at ASP past 10 days. While listeners changed at CCare Ireland, second lady, Helen, was not willing to accept my complaint on ASP. I suggested her to check 2 cameras at Unicorn Pune store. She used smart dodgy words like, only took you 30 minutes for "initial" deposition. On asking what is intial, she dodged. I requested escalation, over her. But Helen said she is the final word. She blindly supported the ASP, who has been unprofessional. They made me lose an important appointment, as well, which I had planned with Customer, in my CEO capacity of an MNC in India. I provided more than 20 minutes at ASP, took 90. Wonder how to now reach to Apple HQ or above Helen madam at Customer care
