Terrible service

after 6 years of continuous contracts with Vodacom, today we reach the end of the journey having you as our service provider. I recently cancelled my contact with Vodacom and instead of receiving a call to confirm the cancelation i get an email that the contact is cancelled. however somehow Vodacom decides to hand over my account. what makes you think you can do that to a client who has been loyal to their commitment with you? So angry, so disappointed
