Disgusting Customer Service

I am extremely disappointed with my interaction with MTN customer service today. I had a month-to-month Wi-Fi contract, which I canceled on April 15th, giving a full calendar month's notice for May. I returned the router to MTN Ferndale on May 31st. Despite this, I was still billed for June.

Since 9 AM, I've been calling customer service to resolve this issue, but I keep getting the runaround. I even contacted the store where I returned the router. The worst part was when I spoke to Njabulo Mthethwa in customer service. He was incredibly rude and didn't seem to understand what a month-to-month contract means. He kept insisting that my 'contracts' (I only had one, but his system showed two) were canceled, but claimed the charge was for the data I received. Anyone with basic knowledge would know that a month-to-month contract runs from the first to the last day of the month, which is why I gave a calendar month's notice.

Aside from his incompetence, he actually threatened to hang up on me. Is this how MTN treats its customers? This is pathetic! I'm so glad I canceled my contract with MTN and will never use their services again.
