Out of bundle data

MTN summarily institute out of bundle billing at 99c per meg and then insist that I was informed by SMS. This practice is extremely *********. It's been occurring since May and has resulted in charges of thousands of Rands. When I discovered this I instructed them to ensure that none of the lines could consume \out of bundle"data.<br> I then also elected to upgrade one of my data numbers to allow additional capacity. After a week I was informed that this line has consumed R20k of \""out of bundle\"" data because the upgrade is only effective on 1 November. This was not communicated when the upgrade was initiated and is also contrary to my request for none of my lines to operate on \""out of bundle\"" data.<br> MTN insist that this practice is within contract terms and in accordance with the consumer protection act. I doubt it but either way its *********."""
