AIRTIME AND DATA DEDUCTED FROM MY PHONE ACCOUNT

MTN have been deducting airtime and data from my phone with me using the phone to call or surf the net.I called their customer service to explain my problem and talked to a call center consultant by the name Vutomi Hlongwani who was rude to say the least.She even hanged the phone on me whilst I was trying by all means to explain to her what my problem is.The little I said was that my data and airtime have been ****** from my phone and she said ur background apps are the ones finishing your airtime.When I tried explaining that my background settings have set to Off so that airtime and data is not consumed she couldn't hear of it.<br> How could one explain going to bed with airtime of 60,100mb data and wake up in the morning with 23kb of data and 17 rand airtime.This has been happening for a while and I used to think its how I use my airtime but being asleep and data and airtime flies off is not on.I am tired of buying airtime and data for MTN to come and ***** it.I think I am well within my rights to call it *****ing.I don't know if MTN wants us to port to other networks .For now I would like an explanation and a refund of my data and airtime.
