MTN - ZERO RESPONSE TO LONGTIME LOYAL CUSTOMER

I have been trying to reach MTN for over a month now, as I'm leaving SA and need to cancel my contract. The immediate response from their 'retentions' email follows:

"Y'ello Guy,

24 hour response time? I've written multiple times for the past month, get the same response each time, but NO ACTUAL SERVICE.

Fix this, MTN. Get in touch!
