Bad service from Mtn Official in Queenswood corner

I lodged the below complain in April and even today I am still waiting for mtn to respond.

I would like to lodge a formal complaint.

On 13/04/2026 I went to Queens Corner in Queenswood to cancel my MTN router.

I was assisted by Chichi. During the process of cancellation, I then decided to also apply for a data sim and Chichi advised that she can use my current SIM and I agreed. I opted for a 50GB month to month contract and she proceeded with the application until she finished. I did not get to check for the SIM because it was late and had to rush back to work.

When I arrived at home I found that my MTN voice minutes and data that was on the SIM was gone and there was only 18GB data and it could not connect to the internet. I then went back to her (Chichi) today on the 14/04/2026 to query about my voice minutes, mtn data and internet connection. I gave her my phone and she connected my phone to the internet and to my surprise she said that i already used 8GB of data and that is one of the issues i need clarity on.

I then enquired about my minutes and data that was on my sim before I app**** for a month to month contract and she said I forfeited everything because I app**** for a new contract. I argued that if she could have explained to me that I was going to forfeit everything I was not going to use my SIM and I would have rather waited for my minutes and data to be depleted before applying for a contract.

I would like MTN to credit my SIM with my voice minutes and data that was there before applying for a contract because Chichi failed to explain what was going to happen to my SIM if I use it for a contract. failure to do so I will take escalate the matter
