Vodacom's deceptive double data

<p>This happened to me on three occasions. Of late, I bought 500MB vodacom data and my balance reflected 1000MB. so i thought since i have an extra free 500MB, let me do some youtube, which i would normally do with caution. After a few videos my phone lost connection and i checked my balance and i found 0.0. I checked on my tablet and i found that i only used 484MB. so they withdrew their illusional extra data. to add salt to wound i called Vodacom to try and understand WTH would they do that, and first consultant took me to the second consultant who said she is transferring me to someone who can help me while she refers to an automated machine that tells me that all their consultants are busy and i will have to call back and hung up.</p> <p>i am very disgusted by vodacom.</p>
