Data being charged out of bundle

Vodacom is charging me data out of my data bundle although I have a recurring 10GB a month product with them. <br> With the initial call on Sunday 13 March 2016 they indicated that I had no active bundle and re-added the 10 GB bundle.<br> <br> However more data charges were incurred after this date.<br> <br> Looking at my current bill I see that I have been charged for 2 10gb recurring bundles.<br> <br> I have phoned in more that 5 times and I have been informed that my call is escalated to the Data investigation team who have tried to call me and failed (why would I avoid or miss calls when I really want this resolved asap? and 2, why is there no record of missed calls on my cellphone?).<br> <br> Vodacom - I just need you guys to call me with a straight answer in terms of the data that is being charged. <br> <br> And by the way, being on the highest package (RED VIP) that vodacom offers still means you get the same *********** service anyways. <br> <br> I hate having to complain on these type of sites in order to get my issues looked into but it seems to be the only way that vodacom takes any notice. PLEASE GET BACK TO ME ASAP!
