COVID ****ed service at MTN

Today I made my 3rd call over the last 2 weeks to MTN to see if I can migrate my line to a better package but it seems like the COVID lock down caused service to pass away as well at MTN. Each time I call I hang on over 15 minutes and the advisor who then answers the line cant hear me. After a few seconds they disconnect me and don't even call back. I am sure your lines should have caller ID to see its a client calling on 135. What I will do is join TELKOM since you guys were unable to assist with the migration and cancel this line next year May once I reach the 24 month mark. Please call me back and discuss my query.
