Giveback promo, more like take back

I normally bought 3Gb data and it lasted me almost a month with the fact that if you load 3Gb bundle you receive 3Gb and 1,5Gb nightshift.<br> Well seems like with all the increases the rate my data is depleting nowadays are also increased.<br> On 31/1/2016 I bought 3Gb data, so I had 6Gb in total and guess what on the 15/2/2016 it was depleted and I thought maybe fault from my side, well I bought 1Gb, which is 2Gb, and today it was depleted after just over a week and the most I have downloaded was maybe 100Mb from my side, the rest was browsing. So I guess Mtn will tell me it is programs in background updating or some sort of malware/spyware I have on my system, well I can assure you it is not the case and your data bundles are getting more and more ridiculous, so I am only left to move to another provider as you are clearly not supplying service you had in the past. The number from which I am using data is ***, have a look at it and verify that there are no suspicious behavior that can be responsible for this from your side.
