Hi @Krishan26,
I can imagine this was a frustrating experience! Have you managed to resolved this and go ahead with your booking over the weekend, or do you need more help?
If it is still happening, it would be great if you could tell us a bit more about what is happening (which device are you using, app or browser, is there an error message, etc). I would also recommend you reach out to customer support on this page www.airbnb.com/help/contact-us/ , and they will be best placed to look into it further for you.
Let us know how you're getting on please! 🙂
Thanks,
Emilie
