Airtime & data disappearing

<p>My data and airtime has been disappearing from Sunday, the same thing happened on Monday and I decided to call MTN Contract (my phone is on a top up contract), they then told me it was because I was on the internet which I was not or my applications where upgrading automatically which is not true, they then told me to go to my data usage and switch off the automatic upgrade, I then told the lady that my phone doesn't have that option and asked her where I could find it, she then told me she will transfer my call to the technical team as she does not know where she can find this on the iPhone 6, while on hold waiting to be transfered the line was cut. I then call the second time spoke to a different lady who told me the same thing and I requested that I get a quotation on how much it would cost to cancell my contract it's been two days and still nothing, I also requested to be transfered to a technically team personnal who would be able to help me which in response they told me they would request someone to call me, which also has not happened. This morning I bought airtime again and its disappered again and all my apps where closed and internet, I am tired of MTN with it ridiculous network and airtime and data disappering. I wouldn't advise anyone to use MTN. I have been a loyal MTN customer but I guess its time to move on.</p>
