Request for a statement costs more than your monthly premium. Terrible customer service!

I have been through bad before but this is the worst, how can you call yourselves a reputable company but it takes 2 weeks for a statement to be processed. I've requested for my most recent invoice on the 23/02/2020, it is now 2 whole weeks since and all I'm getting is a sorry excuse that the billing team is investigating this. What on earth is there to investigate when a CUSTOMER requests an invoice, statement as your weak customer service agents call it. I've spent almost R300 in airtime and your Zanele bot is just as utterly useless. My request is past extreme urgency and has made me lose more money than just the airtime wasted on your putrid customer service line. I am angry because of the continuous blame shifting, incompetence and terrible customer service including spending so much airtime with no end result and just a promise.
