MTS Mblaze - low speed and bad customer care support

Hi,
I bought MTS Mboaze device after hearing of good speed from one or two friends, but what i am getting now is awful, sometimes i click a page and wait for minutes to see it load, or sometimes to open a page i have to refresh it many times.
I was managing with that but the real pain is when i contacted thr custoemer care through online chat, i tried again and again but after asking this question customer care dept. just disconnected my chat, and it happened many times. I was not shouting at them, i was just asking a reason for this, but this kind of attitude, disconnection of chat again and again.
MTS customer support is really a third grade, with no monitoring at all.
I was not expecting this kindaa attitude and after sales service from MTS.
Great MTS go on.
