Lenovo — Incomplete Billing address in my Tax Invoice.

My billing address was incomplete in Tax Invoice provided by online Lenovo store. Billing address that I was provided at the time of placing order was not reflected in Tax Invoice which was received from Lenovo. I contacted over phone many times and emailed to Customer Care & order status 1, but not getting satisfactory reply. When I mailed screen shots of my order history to Customer Care, then they stopped replying. Is this the service of Lenovo, a premier computer Company ? I hereby raised my complaint to the highest authority of Lenovo for correction of my Tax Invoice.
My order no: [protected]. Date of order 10 June 2021.
Regards.
