MTN Invoices still not received

This is not the first year I have this bad experience with MTN. Every year I request that MTN sends my invoices to my email account, but I still do not receive any invoices.

This year again I need to submit my MTN invoices. I requested this on Monday 5 July 2021, but without any response. Today I followed up on my request, after which I was informed that the invoices have been sent to my email address. BUT WITHOUT ANY INVOICES IN MY MAILBOX.

I phoned the customer care line again, to request these. I was informed that I will receive this within 24 hours, but still have not received anything.

I need these invoices by tomorrow 9 July 2021. Will MTN deliver, or fail to send these invoices once again??
