Just got with a R 24,000 bill !!!!!

We've had an MTN cell number for a decade now - no real issues - spend is always under R 1000 per month.<br> The latest bill is a shocker. Apparently on 11 August over a 3 hour period we got billed almost R 24.000 for an our of bundle data rate at just under R 1.00 per MB.<br> <br> This from a number that never uses data. <br> To cap it all, apart from the fact that the out of bundle charge is an absolute *******, there's no was inking that anything was amiss. MTN didn't stop this huge bill from being accrued and we don't even know how this large amount of data was used. <br> <br> We have of course queried it, but the last query with MTN yielded nothing positive (we were billed R 99 for 1 second call , TWICE).<br> <br> Not even slightly happy.
