worst service provider ever

my wife paid an early cancellation of her Vodacom Contract. SHE was the debited by Vodacom. When we called the cancellations department at Vodacom they say her number is now on Prepaid, when we call the billing department her number is still on Contract, how the F#CK DOES VODACOM WORK! NO COMMUNICATION BETWEEN DEPARTMENTS, what a **** service please stay away from vodacom really trust me MTN offers a way better service !
