Bad service for the second time

I went to Vodacom Cape Gate to do a sim swop on my contract on the 05/10/2017, when I checked on Monday (09/10/2017) my sim was still not activated. So I drove to the Vodacom shop to inquire about this, they checked and rep**** my account is in arrears (this is the second time which payments I make on my account gets allocated to the wrong person... Very bad service by Vodacom). Vodacom Cape Gate never contacted me to say we tried but due to an account in arrears, this could not be performed. I had to wait 4 days and drive back and ask them... This after leaving my work number etc. They gave me a huge attitude when I asked why they haven't contacted me... Very disappointed by this branch for the second time as last time I dealt with them I got the same service. And to top it all off while I was standing there being helped by the consultant, a lady came from the back( not sure if she is a manager 'or what) but she came and told the consultant that she saw one of the other customer's bank statement and he won't be able to keep that contract... So much for privacy from Vodacom Cape Gate...
