Mts — No customer care support, speed is too low

Address:

New Delhi, Delhi, 110088

I have taken new data card from MTS and data card number is [protected].
When I took this data card the retailer (Jai Shiv Shankar Communication) told that charge for this data card as well as one month rent is Rs 899/-. If you will call this retailer she will say same thing to you, you can try but I saw on the data card box that it is a postpaid card then how come it includes rental for one month then she said, yes whatever I told you it was right because after using one month you have pay the bill.
Finally I convinced myself that it is ok because I thought other service provider also around Rs 1000 for data card.
I am using Fedora 20 as an operating system and told the same thing to retailer she said it will work for fedora, she was right too bcz it is written on the box that it will work for fedora.
MTS engineer (Karmveer) came my site and told that this data card can not use for Fedora but since I am a computer engineer, somehow I made it work for fedora but now I am facing speed issue and customer care is not supporting at all. I am struggling from day one and complained so many times but never got response from customer care side. Whenever I call customer care they will say "call us after four hours" or our expert will call you but I never got any response from their side. I have register complaint so many times but they always close my complaint without any solution. I requested them to take data card back if they are unable to solve speed issue but they refused to do this. You can see the attache d file which show MTS network it my home. It is varying from 4-5 blocks and I think that is sufficient for good speed. The retailer told me that you will get upto 9Mbps speed upto uses of 10 GB but after taking data card I checked on internet that it is not 10 GB but it is 5GB day + 5GB night.
The speed is so slow that I am unable to open two tabs altogether in system browser.
Customer care is not at all supporting even if I continue my call for 20 minutes and repeated too.
I want this speed issue to be solved or else return my money and take back data card.
I have spoken to following MTS customer care representatives
1. Suman kumar,
2. Himansu,
3. Rahul
4. Many more
