Upgrade turned into nightmare!

Our company has been with Vodacom Business for many years. That being said, we recently experienced extremely poor service from them. We started complaining last year October and still have not obtained any resolution. Our company was contacted by one of the Vodacom partners offering us a great deal on our upgrades which were due around that time. We asked to stay on the same type of contract as the one we had. It tuns out they \downgraded"us to a lower package deal with no device attached. We only realised this when we tried to obtain a laptop and were told that we had already upgraded and thus did not qualify for a laptop. We have been shunted from one department to the next and after many phone calls and emails to Vodacom"
