UPI payments to get anything done sucks for non-citizens

Got WiFi from Airtel the other day. The agent came home without answering any of my questions on the phone and after going through everything, it turns out you can only do UPI payments or pay with a card. Card sounds fine but guess what, international cards don't work. I tried my dad's Indian card, didn't work either, because you're apparently supposed to go to the bank and approve it for online payments. What the fuck? It only works on debit card machines for now. Want to recharge my internet now. Can't pay via UPI since I can't fucking set that up because I don't have an Indian bank account. Can't pay with my debit/credit cards because international cards are not accepted. Can't do Amazon Pay because that also only accepts Indian passports I guess given it won't let me add the last digit of my passport number on there. I can't book movie tickets online, I can't book flight tickets, I can't do anything without having to ask someone to do it for me. It's so frustrating. Today my Uber driver took Rs. 30 less from me because I only had 500's and very little spare change and he barely carries change anymore because of UPI. Well I wouldn't fucking mind Apple Pay or Gpay or whatever except, I can't actually get that set up because I have to be Indian for that. This is so frustrating. Even at the international airport upon landing and international cannot actually connect to the WiFi without an Indian phone number. This is Mumbai airport of all places where thousands internationals arrive every single day. I'm so frustrated with the incompetence. I miss the India where you didn't have to rely on your fucking phone to get things done.
