XFINITY MOBILE WON'T UNLOCK YOUR SIM

I'm going overseas in two days and I made full payment of my iphone 16 pro max, so that I can use other sim on my phone. And when I called to xfinity customer support to unlock the sim for my device, they stupidly argue that they can not unlock the phone before 60 days.

There was no rule or any term was mentioned during the purchase that I have to be with xFinity for minimum 60 days. When I asked the support agent to show me this rule on their website then they said that they are not able to provide the detail.

This is a big harassment and froud by xfinity by applying any random rules on their customers.

Can someone help me how to unlock my phone in this emergency situation?
