Use other Networks not MTN

So MTN lies to people so they can trap them into contracts. I have since been waiting for them to sort out my issue where their sales department said I'll be getting extra data for being a loyal customer. When I want to cancel since this has not been happening, I am told about a cancellation fee???? So I'm spreading the word to Friends and family and will be spreading on social media too.... Move to Telkom, Vodacom, Cell-c.... To think I have been so loyal to them ever since!!!!
