Mtn Momo incompetence

I recharged my Mtn Momo wallet with R600 on the 18th of March with the intention to purchase electricity token, I never received the funds into my wallet but money got deducted from my bank account,I've been trying to get the issue resolved I even sent them proof that money left my account ,but still no feedback from them I keep calling only to be told there hasn't been any response yet to the emails the consultant sent to the relevant person.i really am disappointed with Mtn ,please load my wallet or refund my money.
