Mickey mouse service

Received the worst service from Vodacom ever, not sure if their services are lethargic, complacent or just useless and especially on black friday, was advised that i am due for an upgrade, online system tells me that i need to go into the store, i go over to the cradle stone store and then im told that my contract is cancelled and i need to contact the online guys, this was a total waste of my time and why did vodacom cancel my contract before the 24 months are over????? FSCA will hear about this
