NON-Online Service

I cannot understand how Vodacom can make online services available if it means non-service. Two contracts have been upgraded online and 2 weeks later STILL no delivery of order. They advertise next day delivery?! They contacted us to say it will be delivered within 3 to 5 days, just to phone 5 days later to say again it will be delivered within 3 to 5 days. Contact again to say there is no stock of the phone...phoned again to inform that they do actually have stock of the phone but not of the watch they included in the offer???? Why advertise, make offers available, if you cannot honour offers nor commitments. This is not a single incident as a friend of ours in struggling with the exact same issue!!!
