UnCapped Data Abuse by Vodacom

So as a loyal Vodacom Account Holder that spends on average close to R2000 p/m on my Red Plus account. With a Fiance that lives abroad my data usage on FaceTime is really hi. For 8 months whenever I ran out of data, i received a message informing me of such, (and as far as i am aware) I was thereafter unable to access data: therefore as I can without evidence claim: My contract had its data capped. This all changed over a month where I had bought data at the end of the month and when my monthly cap ran out (i received an sms informing me so) I was led to believe that because i could continue browsing my previous bundle was allowing me to. I only learnt of this mistake when i received a message to say I had used R6000 of out-of-bundle data! WOW! I've been into the shops twice and logged claims and received sms saying i will be contacted by an Vodacom representative. Still Waiting! Can't believe that they can take my money like that. If anyone has experienced the same and succeeded please let me know! Vodacom | you stand to lose out on a R2000 p/m customer forever At The soonest Possible opportunity.
