Hi and welcome to our community ​@Ragini!

This is true indeed: It may happen that your first invoice takes a bit more than a month. After, the invoice will be generated around the same day. If you have specific questions about paying off your iPhone, you can make an appointment to call you back. This way, a colleague of mine will call you when it suits you, and the right verification can be done. This is important for safety, because it's about financial information. My colleague can help you further with the possibilities for the payment.

Thanks for your reply. I understand it takes a bit more than a month. I contacted the customer care support multiple times, they are not sure when the invoice will be generated. Looks like an indefinite time. And they also say that without the invoice ,iPhone cost cannot be fully repaid which is in turn blocking my mortgage process. Is there any way to pay off the iPhone cost before the invoice gets generated? I am ready to go to a store if this can be sorted out there.

I also tried to schedule an appointment for this using link from your reply but I couldn't find any related topic to schedule one. It would be great if you can guide me.
