MTN Number Marked as Spam by Truecaller

I am an MTN Nigeria customer and for more than three months now my phone number has been marked as spam when I make normal calls and on WhatsApp. People I call see my number as spam, which is embarrassing and makes it difficult for me to communicate properly. In the past, I have used this MTN number for activities that may appear like bulk or marketing use, and I believe this may have caused my number to be classified as spam. However, I am now facing serious problems because friends, family, and other contacts are afraid to pick my calls when they see the spam warning. Through this complaint, I respectfully request a full investigation into why my number is flagged as spam and that MTN Nigeria, together with any connected platforms or spam databases, remove the spam tag from my phone number. I want my number to be restored to normal status so that people I call no longer receive any spam warning associated with my line.
