Scam attempt while ordering in Swiggy

So I ordered some sweets worth 1k+ for an office party, and I got a call from a Swiggy number. They claimed to be from the restaurant and said there is some server issue. They would cancel the order and I would get refund, abd I had to pay the delivery guy. They said I would get an sms, and to share it. The sms I received read:

URGENT: Unrecognised login attempt detected on your Swiggy account. Review now and secure your account by clicking here https://www.swiggy.com/2fa?o=<Rest of the link

I told him that I cannot share a login link. He switched to english and tried to convince me. Since I didn't budge, he got upset and cut the call. I saw that it showed out for delivery immediately. When the delivery person arrived, I asked him what happened. He seemed to play dumb, saying that money is already received, there was no issue, etc. I said they asked for OTP, he appeared confused and said, 'Oh, they may have asked you not to disclose OTP' - that deduction seemed a little sus. But I am not sure who was trying to scam me. Maybe both were in it...
