Amazon India — billing address was changed in invoice. not the same as I put when I ordered.

Order id: order #[protected]
Problem:
I bought oneplus 7 phone from business account on amazon.in. During order i gave billing address as company address and shipping address as residential address which an be seen in order summary (Can be seen in attachment).
But when the mobile was delivered, the invoice generated has a fault.in invoice, the shipping address was but in billing address.
When i chat the customer care employee about this issue they said that it is their policy for changing the shipping address into billing address. But what has happened with me was opposite and when i told him that then they said that is their policy for this also. Then doesn't the policy of amazon business is in contradiction.

Resolution: provide the invoice with proper billing, i. E. With the billing address which was stated which is our company's address. Billing address should be the company address only as business address is fixed and all the order placed from that account is for that business. And check the policy of amazon business account of such contradicting policies.
