Worst. Review on MTS MBlaze

On the first month of my purchase of MTS Mblaze Ultra , I was getting a speed of 2-2.5 mbps and I was satisfied with that. But after 1-2 month its speed keep on decreasing. And on this month I was getting speed max upto .6 mbps. Some time speed is so low that you can not even send a Whatsapp message. Loading a Google page take so much time that you can easily make a coffee in that time. My 4 year old 2g network was better then this at that time. Then when I requested them for disconnect the service each and every day they were increasing the bill amount and at last when I said I won't pay for unused data they said they will take legal action against me. I felt what the wrong with those idiots I was saying from past 15 days that I don't want your connection please stop the service they said sorry for inconvenience but it is companies rule. Never ever prefer MTS worst data pack ever
