uncapped my ****

I am a customer mtn as they have good coverage all over sa. I bought a tablet that required data for use, i then found that they have an 24hour uncapped bundle for R40 and i found it to be affordible but im very disappointed as i found that my apps on my phone would run for 5 mins then i recieve an sms stating my data is depleted. I then phoned the *** customer service and a very rude mandy somthing answered i then queried why i recieve the sms shortly after loading the data and she then responded with the following comment \eish you people must read the terms and conditions cause yhe uncapped is only 50mb of data for browsing not for running apps or downloading"so i ask you where is this so called terms and conditions onnthe *141*2# site and why advertise it as uncapped when its not. You guys are ripping people off and your staff in the call centre should not work with public if they dont have manners i am taking this complaint to the media aswell"""
