IMPOSSIBLE TO GET INVOICES EVERY MONTH.

MTN I AM SO SO SO SO FED UP WITH NOT BEING ABLE TO GET MY INVOICE FROM YOU. EVERY MONTH ITS THE SAME ISSUE. I TRY 1000 TIMES TO EMAIL THE INVOICE TO MYSELF VIA THE MTN APP AND IT NEVER WORKS. I CALL MTN AND LISTEN TO A PRE-RECORDED VOICE FOR 7 MINUTES AND STILL CANNOT GET THROUGH TO A CONSULTANT BECAUSE WHEN I PRESS "0" TO SPEAK TO A "SERVICE CHAMPION" THEN IT SAYS INVALID SELECTION???????? THIS IS UNACCEPTABLE. ALL I WANT IS MY RECENT INVOICE - WHY CAN YOU NOT EMAIL INVOICES ON TIME LIKE EVERY ONE ELSE. CAN SOMEBODY JUST HELP ME?
