MTN Network is a ****!!!

In August 2024 I took up a month to month contract with MTN. They didn’t deliver within the agreed time frame and I had to travel; when the courier delivered, I wasn’t home and they returned back. At that time I had already paid my first instalment and I have since been asking for my refund. None of my emails are responded to. When I call their call centre, I’m told that I need call on the number I have a contract with, not someone else’s. How can that be possible when I don’t have any MTN sim? If you want peace, stay away from MTN, they’re the biggest **** ever!
