Data usage not accurate

<p>I bought 10 gigs of data like i usually do monthly. However for the month of July it only lasted until the 7th July as opposed to the 20th. I logged a complain with vodacom and a lady by the name of Watheeqah Wallace called me. After we did our reviews it showed that about 5 gigs of data has been used from my device. She said she would reimburse me with 8 gigs of data. I was also adviced to download a data tracker app to which i said it was fine, i further told her that i always have the same issue with vodacom and i will be porting to Telkom an=s am tired of complaing. I am disgusted to say that vodacom only loaded 1gigs of data back to my account, poor disgusting service. I want my data back. </p> <p> </p>
