Vodacom just totally useless!!

Spending and average of R5000 per month, can upgrade but have to pay in some ridiculous amount for a phone that I never had to do! With a credit score of 951 my credit history is not good enough! Keeps getting phone calls about arrears account even a week after I have paid, but try and call them,it will take at least half an hour to speak to the right person just to find out that they can't help you!! Absolutely useless service and staff! And not the only one that have experienced this. Practise what you preach Vodacom, this company knows @#&* about customer service!!
