POOR service at MTN MOMO . Keep away

I paid for car registration at Momo on 23 June 2020. There has been no response. I have sent 14 emails that were received but never answered. After 6 weeks, the car registration is not done and they have not refunded the money despite requesting over emails. Customer service was as poor as emails. they kept on giving e different numbers, each one not knowing what is going on, mUsic goes on up to 22 minutes with no answer. extremely frustrating. never to use MOMO again ever
