Yello data false advertising

Watch out for a company telephonically offering cheap Mtn data called yello data. This was copied from their web site :Once you have run out of your bundle data, you will be capped until the 5th of the following month. You will receive an SMS once your limit has been reached. There will be no unexpected out-of-bundle charges. For continued use of data services, you will have to revert back to your default APN settings. ...<br> No such thing. All of a sudden I get exactly what they say will not happen R365 bill for 500mb out of bundle data cost ! No warning and no cut off. Call centre says they can't cut off and yet the months before they did. R365 - could have got a couple of GIgs for that ! Cancelled immediately. Absolute ****.
