Out of Data Limit Lock a big sham!!!

Vodacom's out of bundle limit lock does not work. I had mine set to 0.00 in the hopes that I would not use any airtime unnecessarily but low and behold the limit is a sham. I was under the impression that I wouldn't have to worry about airtime being used for data but oh no, Vodacom is not complying to rules set out by ICASA. Another prime example that companies like this can do as they please and squeeze money out of the poor! I even set my limit to 200.00 today and back to 0.00 and still no difference! I want all my airtime that I wasted reimbursed!! I'm waiting for the automated responses that your social media team will copy and paste. Here goes another fight with another ****** bag Company...
