South African Incompetence at its Finest

I've been fighting with DSTV to get proper invoices since January 2019. I used to be able to get my invoices online, but they haven't been uploaded into the system on the DSTV site since January, for service in December 2018. It's now April, and I can't get these *****s to get me invoices no matter how many times I try. The last time I tried was April 8th when Londiwe assured me she would get me my current invoice within 24 hours. Then she just disappeared and won't reply to emails anymore.

I need these invoices because my employer reimburses me for them. But I can't get reimbursed if I can't get my invoices.

I don't know why it's impossible to get a receipt for money I have paid. This is South African incompetence at its finest.
