Bad service from MTN

I ordered a MTN router online on the 23rd of November 2024. First of all I only received the device on the 3rd of December after the expected delivery time was between 3 to 5 days. Secondly the delivery was a mess. After been told the delivery will take place between 12 an 1 it was only delivered at 16H30. After having to complain several times the sim card was only activated the evening of the 4th. The router worked 100% for a few hours during the evening and then went offline. After several attempts to contact MTN the sim was again activated just to be barred again after a few hours. I was then told that I moved the device from its registered location whi h was absolute nonsense. After several calls and Makin enquiries on WhatsApp chat en messenger I manage that my registered address was captured incorrectly. After several attempts it was corrected but still there is no internet connection. More calls and messages later and still no access.
