Unhappy customer

My husband is struggling to get his money from MTN that they deducted for almost 3 months now, and he contacted Mondo many times and every time they notify him that they will address the matter. Last week Mondo notified my husband that they have send MTN an email to let them know that my husband must be credited. Mondo gave a reference number to my husband but since last week, my husband still haven't received his money that they owe and no one phoned him or let him know what is going on. This is really pathetic from MTN and Mondo. They are quick to deduct money that they shouldn't have, but when they have to pay your money back, they take their time and don't worry about you. The money that they deducted so far is over R3000!!!! They rep**** with the message below that I pasted, but we never heard from them again and still waiting for our money. Mondo's reply: 28 Nov 2022, 10:48 Hi Juan, Trust you are well. Please note that your MTN line has been cancelled and deactivated.
