There is no argument that MTN is one of the most annoying network, they can subscribe you to their services without your consent, and when you try to call them so you can opt out, they’ll keep you on a queue, after staying on the call for up to 30 mins, you may eventually give up.
But now, if you have any Issue or questions for them, you can now chat with them on your whatsapp. But Note that, If you send any Irrelevant message or any Broadcast message to them, you’ll be Blocked Immediately.
So these are their customer care numbers below;
So start pouring out your anger on them, but use caution though *winks*
