Bad service after debited my bank but can't credit.

On the 19th April I was transacting on the Mtn Momo app via Ozow to fund my Momo account for R2500, then I received a message saying transaction failed however money was debited from my Capitec bank acc. I did follow up with Capitec n Ozow they confirmed transaction was successful. I logged a query with Mtn Momo providing all the relevant documents and info, was told 72 hours will receive feedback. No feedback after 3weeks even now, tried calling almost a day after but get told lies and stories. Tried socials till date no refund. Mtn pulis give me my hard earned cash and want to cut business ties with you after. Your service is pathetic and terrible...very ****ed off 🤬
