Shame on you Vodacom

I have received a sms from Vodacom earlier today.. tonight I responded on the sms.. First.. buy 1gig data for only R39.. so I decided to buy the 1gig data.. and right at the end.. after I have paid.. I were informed that the data is for night owl only.. now isn't this a misleading add to the public user.. Vodacom should have mentioned "night owl" in the first sms.. Second.. then I bought R100 airtime online.. I got my R100 airtime plus R100 airtime to be used before 23h59 tonight.. I had 1 call to make.. so I made the call.. check my balances after the call.. the cost of the call was deducted from my normal airtime and not from the free airtime.. now isn't this *****..
