The date of mobile phone invoice is wrong. What about the warranty?

The dealer is required to issue a new invoice. If the warranty is carried out according to the invoice, it is obviously impossible to guarantee it until June 2008 to 10. This is the dealer's fault, and you can't bear the consequences. However, Nokia found that your mobile phone is still under warranty after sale, and users can make a warranty without providing an invoice. After all, people don't go around with receipts for buying mobile phones when they go out. However, if the invoice is not provided, it is only for the host warranty, and the mobile phone configuration must have an invoice and a three-package voucher card.
