OP: " have prove my product is real."

Good. All Amazon wants to see is your commercial invoice, not a receipt or an on-line credit card order.

Amazon knows what an invoice includes. An invoice is used when Your USA business has a retail commercial credit account with the manufacturer. Most all invoices include all of the following:

- YOUR: business name, business address, business phone, sales tax exempt number, your EIN number, your credit line, and terms of sale

- MANUFACTURER’S: address, phone, EIN number, account Rep’s name

- PRODUCT’S: quantity, SKU-Model number,

- DISCOUNTS PROCESSES ON THIS PURHASE: quantity, sale, specials

- TERMS OF SHIPPING: method, who pays, company used, tracking number

- TERMS OF PAYMENT: 30 days, 60 days, 90 days, interest assessed

Some have more, but they all use the same basic format. Even when you call and make a small online order and pay by credit card, an invoice is still sent to you separately containing all of the above.

If you purchased the items from a distributor using cash and carry, or on-line with a credit card, and paid sales tax on it, you are not buying wholesale from the manufacturer.

If you do have a video chat, and do not have a commercial account with the manufacturer containing account numbers to display, you will look a little foolish and show Amazon, they are correct in their assumption.
