data loss 5GB in 1 day

I have a 5GB data bundle with VODACOM <br> this is the second month that my data has disappeared , the 1st incident happened on the 12/08/2015 when the Vodacom was shocked by Microsoft Windows 10 and my comp. still runs on Windows 7 Pro.<br> I was re issued with 5GB of data of a massive argument and telling VODACOM that I will go to Hello P. and then I was re issued .after I bouth 1GB myself.<br> the 2nd time was the 2/09/2015 when I lost 5GB in 2day's and VODACOM 5GB expired that same day.<br> I have spoken to a team leader Mr Musa , Gerhard from P.E and everyone sells me different lies and promises.<br> my 1st call was logged on the 3/09/2015 and there after I was re issued with 2GB and my Vodacom Mible WI-FI R206 was off and then I have used 1GB 50% , I have ask VODACOM so many times to explain how that can happen that you can use data after your ****le is shut down. I was re issued with 1GB of data .<br> My question to VODACOM why do you keep on replacing some of the data if it is not your fault?<br> at least expire my contract in 01/12/2015.<br> from the 1st time I logged a complaint I have ask VODACOM to phone me on my cell and I have told the that the number in questions is a ****le no commication
