MTN Newtown Junction mall has horrible service

I did not know purchasing a router would get me into such a nightmare all because of the incompetency of MTN Newtown Junction sales people and now handed my name to Underwriter Debt collectors. I returned a WiFi Router which I purchased at the MTN Newtown Junction Mall of October 2022 and returned the device in April of 2023 when the Network Coverage could not help so they opted I return the device and the contract will be canceled, mind you they chose to cancel this contract.

The sales person at MTN Newtown Junction mall is the one who sold the device to me and is the same person who I returned the device to but she did not follow protocol of filling out a Customer Return Document form which I was meant to sign and the MTN headoffice is the one made me aware of this when I returned on 10/01/24 for a follow up. My account has been handed over to the debt collectors upon which they say I owe MTN outstanding fees from the day I returned the device because this lady actually did not follow the correct procedure and I did not get any IRM number to show that the device was returned and for my return of no service to be returned. No one at the MTN Newtown Junction mall can assist me because the Manager is never in and the same lady who sold me the device also has not been in store. This very frustrating as you can never get the manager of the MTN Newtown junction store or any superior to assist when they have caused such a mess for me. Worst experience ever as a customer!
