Vodacom: greedy old monster

I bought R140 airtime for my DATA router after 22:00 last night with the aim of buying 2GB data when I wake up this morning.<br> I wake up this morning only to find that my balance is now R10. When I call customer \care"I'm told the airtime was used up to run updates on my phone (which I did not disconnect).<br> Why is a DATA router using AIRTIME??? Is it because this greedy monster called Vodacom only cares about filling their pockets and couldn't care less about the customer. You want to make a buck"
