Beware MTN is deducting airtime at OOB rates in contravention of ICASA regulations which came into effect 1 March 2019

On 18 March MTN gave me 500MB free data valid for 7 days. On 21 March I did a balance check and I had R54.55 airtime and 448.05MB data. I used less than 200MB of the 500MB data bundle before it expires as my phone is usually connected to my home wi-fi internet connection. On 6 April I did a balance check and I had R6.38 airtime. I had made no phone calls that would use up my airtime. I did not opt into any data charges that may be deducted from my airtime as per the ICASA requirements. Technically, I should not have had any mobile internet access. To test if this was true, I did a speedtest using moble data and I had mobile internet access. After the speedtest I did another balance check and I had R4.66 airtime. That means R1.72 airtime was deducted for a speedtest that used 117MB of data. So MTN has been *******ly deducting from my airtime for mobile internet despite this being against the ICASA rules. My number should have been blocked from internet access and OOB charges, not allow me mobile internet access and deduct it from my airtime at the OOB inflated rates. I really don't care if you refund me or not. Just the amount of time it took me to write this review I've lost many times over the amount you've *******ly deducted from my airtime. As the saying goes, time is money and I bill by the hour for my services. What I do care about is that thousands of subscribers see my review, check their airtime balances and confront you regarding your ******* deductions. Also I hope someone from ICASA reads this review and takes MTN to task. I can prove everything I have said in this review. I have screen captures of the dates and balances mentioned above, the speedtest actually running when I was not supposed to have internet access and the amount of mobile data used according to the My Data Manager app.
