Data missing and no activation on sim

Upgrade my modem 3gig day and night only download for two nights during 12-6 (30min and 15 min) all data gone phone call centre off line response for two days straight finally got hold of someone been told I am not activated so how did I connect to the net put me threw to after services just that the phone been put down in my ear upgrading with Vodacom was the worst mistake if only Vodacom bosses can be so quick to response to customer complaints as they moan about whatup and skype there priorities is so clear money and get you the customer into a deal after that ...
