Rip-off cellular network!

Vodacom is literally the worst network. I purchased 1GB on 19th July, besides whatsapp bundle and social bundle which was already active on my network. On the 20th July I recieved a message that my bundle had depicted. Checked my vodacom app to see what was using up my data with that 24hrs and there's nothing recorded that sums up that amount! This is not the 1st or 2nd occasion this had happened! The 1st occassion when I found out that Vodacom was ripping their customers off was when I opened my contract with them which came with a wifi modem. I had packed the modem with its sim card along with my laptop away since I was shifting therefore was unable to use the wifi provided. I went onto my vodacom app and discovered that my 10Gigs was now sitting on 2Gigs with nobody using it! When I called to query nobody could answer me, instead they told me they opening up an investigation and will get back to me. 3days later a Team Leader contacts me apologizing n replacing the data, which was then used up again with the next 3days! Vodacom is disgusting! I will definitely keep my number but change to another network. At a time like this we cannot still be getting ********** by our network, besides everything else! Your reputation has diminished!
