recent high data rates

<p>I have been incurring extremely high data usage over the past 3 months which I queried to my mobile network to try and find out the cause of such a drastic change. My usage changed from 1.5Gig monthly to 4Gig without changing the apps and without increasing my average usage time on the apps.</p> <p>I questioned the sudden increase in usage because I have always closed my apps after using them and I used my data for browsing and not to download nor watch videos online.The first month when i picked up the issue I did not lodge a complain because I was not monitoring my usage.</p> <p>Since then I stated monitoring my usage and I realised that I my data gets depleted way fast (e.g I bought 1 Gig on the 2nd of december 2016 and it was depleted by the 5th of december just through browsing.)</p> <p>I called MTN to enquire and complain on the second month and I was advised to restrict background data usage on my apps which I did, although this was never an issue even during the times when my data usage was normal.</p> <p>I encountered the same issue during that second and the third month and I lodged a complain twice to MTN and I did not receive the help I need and the call centre agent assiting me on the second call was also very rude.</p> <p>MTN said the high data usage of (3gigabytes) which I incurred (over 15days) is as a result of the changes implemented by facebook and that my usage is now based on the number of friends I have and their usage of the app which I stated does not make sense as people I know on other networks use similar apps twice as much or more than me yet they spent less.</p> <p>Then I was told that those are other service providers not MTN.Then I stated that if that be the case then MTN's rates were hiked as they were not always like this.</p> <p>I was also emailed regarding a handset upgrade of my other line and I responded stating that I cannot upgrade with them.I made them aware of my unhapiness regarding my sudden extremly high data costs without change in my way of usage and I did not get any response. </p> <p>The rates are extremely rediculous as I have used up 3Gig of data halfway through the month already which is excluding the airtime that gets used up each time my data gets depleted.</p>
