Unexpected high phone bill in a few min!

All smart phones these days have data monitoring devices. <br> <br> on the 30th of October I tried to give my Girl friend access on the internet from my phone so that she can open her face book. <br> <br> Without out me knowing, my Laptop connected and my Windows 10 decided to do a 740 megabytes update!<br> I took a screenshot of my phone to prove the sudden spike on the last day if needed. <br> <br> My phone bill went from R300 to R1150 in a few minutes. There is no way that I can afford it. I am currently unemployed and I cant be soft lock due to reaching a limit, cause i am busy trying to search for work. This will break me...<br> <br> I have send Vodacom a mail but still no reply, hoping that we can revert these extremely expensive out of bundle data costs. I will be fine if we can revert it, or at least just convert it to a 1 gig data bundle for R100 or something instead of >R700 data charge!!<br> <br> Please get in contact with me asap. I have been on contract and a client for the last 10 years and this is the make or break. Please assist!
