MTN, stop fleecing your customers!

MTN! This is an organization that turns into Dr. Jekyll when you get to the end of a contract. I’ve been surprised by unanticipated charges now that I want to cancel my contracts that are at the end of term and no longer required. What I fail to understand is why MTN’s business model is to fleece it’s customers at the end of the “relationship“. Do they not realize that this practice does not encourage any future dealings?
