MTN MOMO IS A ****!!!!

I paid R720 for the renewal of my car license disk on the Momo app and it has been almost 3 months. Haven't received anything!! Emailed them then they send you an sms for about 3 days saying they haven't forgotten about you and that it's in processing. But still havent received anything till this day. I am very disappointed and I want my disk or my money back!!!!
