Simply Useless!

I have always been a loyal Vodacom customer with bills always paid on time. i never gave then any issues. All of a sudden my data contract gets cancelled and no one can tell me why. i have called them several times and i keep on getting told they will investigate and get back to me and no one ever comes back. It has been 3 months now and nothing! First time that i ever needed assistance and the service has been beyond pathetic! What a useless cancellations department that cant give me answers, not to mention their customer service department as well, just useless. Are they even allowed to cancel without my consent, what then is the penalty fees to Vodacom! Is works both ways VODACOM!!! I have never seen a more useless company. they deserve a negative rating
