Locked line for outstanding balance of R128.

Vodacom locked 10 of my lines for an outstanding balance of R128 owing on my bill which they can debit at the end of the month. It is really disappointing, being a Vodacom customer since 2004 that they would go to this extent. Vodacom service is really making me change my mind about what supposed to be the best network in SA. They run their network and services over automated systems, yet have a call Centre full of people that cannot override or make changes to the billing services. What is the point? Furthermore there is a R10 charge on every line to be reinstated. Seriously? They should really pay attention to their premium clients.
