Poor Client Experience and Service

I am due for an upgrade but because of low portfolio status Vodacom refuses to give me an upgrade. I am on one of the top packages and have been a client at Vodacom for the past 6 years but now all of a sudden I cannot upgrade. This service from Vodacom is very poor and I would think twice before entering a contract with Vodacom. I pay every month but should you just pay to late one month they immediately cut off the line. But when it becomes time for your 24 month upgrade then it is a big problem. The end of the day they are sitting with the power in hand and they know it so that is why you will always just be a number with them. Very poor client service and satisfaction.
