Jai Mata Di Music Corner (jmd Electronics) — Fake bill

I purchased iPhone 16 Pro Max from a shop near my home and they told me it a legit device and charged me 71, 45, 000. Today, I got to know that the bill is fake. The shop keeper purchased the phone in black from Dubai and sold it to me in India and charged me 18% GST on the bill. Please look into this and take appropriate action.
