Need to change MTN get a new costumer service its 2022

So I come here to express my disappointment with the MTN service I have received. I have been using and recommending MTN since I had my first number with them more than 13 years ago. I feel defeated to see so many complaints similar to mine. I called more than 10 times, facebook chat and emailed. They respond but they don't seem to understand the customers' needs. Instead of concluding the matter, they would rather say they will call you back or send an email that acknowledges your email with no significant response to the issue. NEVER WILL I VIEW MTN THE SAME. NEVER WILL I ANSWER my phone by YELLO. I am definitely not renewing. Bye bye yellow!
