Vodacom *****ing my data

disappointed with Vodacom. My wifi rental is approx R300 for a 10GIG night owl. Suddenly last month I around the 16th of Feb 2018, a bunch of sms es to my wifi router (without LCD Display) telling me that I have run out of data of course I didn't expect it as I have 4 devices each with their own data plans and 10 extra gigs was more than enough. I Needless to say I got saddled with a bill over R6000. I called to querry but no help, so I paid it. But guess what This month as well today in fact, i checked my data usage on my wifi and discovered those smses on the 17th telling me the same thing and again today I was told that i am R2700 over. Thanks Vodacom, I've been loyal since 1998. I think that I've just had enough. I called this afternoon for 20mins, recorded a call suddenly I was put through to a rating your service machine and the call was dropped. When I signed my wifi contract I had asked them to soft lock the sim when the 10gig limit was reached and this worked for the first year. I had also requested notifications to be sent to my primary number, which also stopped last year. Thanks again Vodacom. If there are ******* taking my data, I think that is vodacom to boost they revenue. My combined bills over my lines average over R2000 monthly. But I guess thats not valuable enough vodacom

Thanking you Kindly Harold Paton
