MTN and Poor customer protection

What an utterly disappointing user experience from MTN. So I have been using my MTN number for over 15 years now, and recently unfortunately my device got messed up and did not have a phone for several months. I would however use my Simcard intermittently especially for transacting on the Momo app, as well as MTN app.

To my surprise when I finally do get a device, I try using my simcard and I find that my number does not work, I subsequently try logging in my MTN momo and profile to try and get assistance but I find out that they have been completely deactivated. When I reach out to customer support, I am told that my number has been realloacted to another customer because I was not active for some time.

Now this possess a security risk on my end because the aforementioned number is linked to my banking profiles, social media as well as any other digital and physical platform or institution that may require a sim card. Thus due to a month or 2 of none usage I have lost a huge part of my identity.

This number is a part of my digital footprint and history. And for mtn to give it to another customer so easily. Of which upon further investigation I have found to be false because when I check the RICA registration for the number, it says not registered. Thus MTN has been providing me with a false narrative that my number has been reallocated

Furthermore what is the purpose of RICA, as well as MTN's ID of which has my facial recognition data if a number that is linked to your ID can be so easily allocated without prior notification as I did not receive any notification that my simcard will be deactivated. The above experience has put me in a position where im easily susceptible to ***** and mtn does give a damn
