*********** staff and poor service

During July 2021 I app**** online to upgrade my mobile Wi-Fi router only to find out that a new contract was opened in my name, which I did not ask for. I only requested an upgrade on my current device. I returned the router back to MTN Key West within 7 days. I requested the contract to be canceled. After a long struggle, the contract was canceled on 26/10/2021. I am still being charged for this contract and was informed by MTN on 2/12/2021 that I am being charged for an early cancelation of the contract. I did not request a new contract. I phoned Mondo on the same day to have the credit passed to my account, the lady (Asepi) promised to call me back, no feedback yet. I called again and held on for over 15 minutes, no answer. I want my account to be rectified with immediate effect.
