POOR SERVICE!!! PROBLEM STILL NOT RESOLVED

My husband bought 2 Blackberry handsets 2 years back. The contract ended on 31 March 2015, he was offered another package that and took it. BIS on its own is R59 and if we paid just R10 more we would receive a package for R69 that consists of BIS and R100 airtime. After calling the call center and being on hold for 1 and a half hours the 4 consultants we spoke to could not help. They did not know about this offer and said that we should call in the next day. There are no managers available whenever you ask to speak to one.Finally after calling in again a consultant was fami**** with the package then helped us to lodge a service request and after 24 hours still not resolved. OUR BIS IS STILL NOT WORKING. Received an sms that the CIC depart is investigating. No indication as to how much longer we have to wait. This is unacceptable service, i am very upset and have waited more than enough for vodacom to solve the issue.
