Paid for a service I never used – MTN still hasn’t refunded me

received an MTN Wi-Fi router in January 2025 through Mondo. The device never worked and I returned it within two weeks. Despite this, my account was debited monthly until September 2025 due to MTN/Mondo’s internal “backlogs”. I paid for a service I never used. Mondo later processed a refund into my MTN account and instructed MTN to transfer it to my bank account. MTN never transferred the money — and the refunded amount has now disappeared from my MTN account completely. For four months I have emailed and called MTN repeatedly. I was promised feedback many times and received none. Recently, MTN referred me back to Mondo, and Mondo referred me back to MTN. I am being sent in circles with no resolution. MTN has: • billed me for months after return • failed to cancel my contract on time • lost my refund • ignored my emails and calls • and is giving me the runaround I am still waiting for my money and written confirmation of cancellation.
