1GB data free for new customers

Received a message from Vodacom that they gave me 1 GB data to use in 3 days time, at Midnight my data expired when in fact the message I received said till the 20th. So I should have had the data Today being the 20th of August till 23:59pm and then only expire... however when I phoned customer care they said it's a promo and they do not say when the promo will expire, but I have a message saying till the 20th and I've only received the message on the 18th. That's only two day and not three as the message states. Vodacom is scaly and they've done this before. When will Vodacom be a anti *******ion provider, why is that Vodacom ***** people over and over and still say that they are the number one providers... Vodacom is a bunch of ****** that doesn't care about their customers, all they care about is getting more clients with false promotions and getting rich off of their customers, doesn't matter to them if they ***** us as long as their customer list is growing they will keep *****ing myself and new and old customers.Vodacom A bunch of ******. And not helpful at all.
