My 1gig taken and poor communication,disgustig

<p> Hi guys MY name is Ernest,on the 25th Thursday I went to  vodaworld to redeem MY points for a phone,I got  a phone at about 15:00 and I bought 500mb for downloading apps,and I left on  Saturday during the day I bought another 500mb and Saturday nite I got a message from Vodacom thanking me to have bought a new phone and they now giving me 300 BONUS and 1gig to DOWNLOAD apps,I then wrote email to them that I ALREADY purchased 2 500 mbs on Thursday and Saturday,now MY gig is taken away and I am not happy about it CAUSE the bookshop people and Vodacom knew that I am gonna get a free gig to download but they never informed me about that,which Is I think is nonsense CAUSE their job is to communicate to clients and advise</p>
