Call Limit Lock & Bill

Good day,<br> <br> I hope Vodacom can urgently assist me.<br> <br> Usually I use my phone as a Wi-Fi hotspot to work on my laptop, this doesn't take a lot of data to do, basically to check emails and submit programs remotely.<br> However, yesterday when I was doing some work, another device connected to my Wi-Fi and without my knowledge started downloading updates. Only after some time a data warning appeared on my phone showing that I used around 5GB. Shortly after this I received messages from Vodacom that my account is at 70%, then at 90% then that my phone reached the Call Limit Lock, so I can't make any calls or receive any messages.<br> <br> This morning I managed to check my balance and it is at an insane amount of R6500, where is usually is around R1500 by the end of the month.<br> <br> I made a terrible mistake and can't possibly afford to pay this amount, is there any way Vodacom can help me? Possibly, rather let me pay the 5GB at a bundle rate rather than out of bundle.
