Worst customer service

Vodacom is the worst network provider that i ever came across. Their customer service is terrible. I never heard of a network provider that cancels a contract that is not in arrears and worst of all cancels the number without letting their client since 2001 know. Monica in Customer service promised me that her supervisor will call me before 5pm today and still i have not received a call. In the interim i had to borrow a sim Card from someone so that they can get hold of me,let alone my family and friends. never will i renew my contract with them again and i advise all my friends and family to do the same.
