What is the story of the tax invoice and account statement?

El-Shennawy offers you a very rigid feature, which is to issue a tax invoice, not an account statement, and put a million lines under it. What do I benefit as a customer? In this invoice, you guarantee your legal right in the event of a manufacturing defect in the product Do you know that most of the mobile agencies now do not accept the mobile without the tax invoice?? Do you know that when you return to the store from which you purchased the product with an account statement, if you ask him to miss it, he will pay you 14% more than the money you paid in the product Why bother and fall between the dealer and the power of attorney when you can buy from a guaranteed place and take a legally approved tax invoice that guarantees your right.
