Bad customer service and complaints department

Poor Service from MTN. They actually stole 5400YB from me. I did buy 3 X Bundles in the month of Dec 2025 and Jan 2026,to this day, I haven't received my Bundles even thought after they **** to me that they Refunded about 1900YB that never reflected on my App. I am irritated and angry as their Customer Service and Complaints(Don't even think it exists) are the most useless, all the Emails sent and lies about that they escalated the matter is irritating and boring. They must take accountability and won't stop reporting them to every Ombudsman or organization as they are reaping their clients off.
