CAN I HAVE MY INVOICE PLEASE

I bought a table for work purposes via Game online, i received my item without an invoice, ive been calling and emailing them to send me the invoice so i can send it to work as i need to be reimbursed for that purchase, the ladies that ive been speaking to from Customer Care are not so helpful either because they took my email address last week and said they will forward to the online team.

The level of incompetency is unacceptable, i mean COVID can't be the reason people are not doing what they supposed to, that invoice was supposed to be send with my goods. It's really annoying having to call over and again for something that should been done right from the get go.
