Poor service by MTN

I'm writing with great disappointment on services from MTN. I have been a loyal customer of MTN for years and what I am experiencing now is upsetting and unbecoming. On the 2 Sep 2022, my phone was blacklisted by MTN without any warning. I called MTN numerous times, I even did a sim swap. I ended up taking my phone back to SAMSUNG thinking that my phone was problematic. SAMSUNG informed me that my phone is blacklist. I went back to MTN and they inform me that indeed it is blacklisted. I was asked to write an affidavit and provide proof of purchase, of which I did. My phone was purchased from an independent outlet affiliated with Samsung. All I have with MTN is a sim contract, meaning the handset does not belong to MTN. I have been using this handset for two years now. One of the staff from MTN promised to unblacklist the phone after following up with MTN and being told that it will take three days to activate. After 3 days, I received a call from one of the staff from MTN who told me that their Legal department is refusing to unblacklist it. For what reason I don’t know.

This is such an inconvenience as I have been deprived of my right to enjoy the usage of my phone which I bought and have proof of such. I have sworn under oath that it is my handset but MTN has a different view. MTN could have verify the purchase with the manufacture (Samsung) who is most willing to attest to the authenticity of the purchase by myself. The handset in Samsung is under my husband's name who bought it for me as a gift. All, I received from MTN is that they can see that the device is under someone's name and not yours. Despite, providing MTN with all the necessary information, they still haven't resolved my issue. Surely, if my phone was ********** device, SAMSUNG could have informed me and they would have the right to blacklist my phone. My contract with MTN is due next month, I will be leaving MTN and going to another service provider that would take me seriously. Clearly, MTN does not care about their customers which is petite because I did love the service provider.
