Tata Docomo — Internet speed is too slow

I'm using 2g internet on my tata docomo prepaid sim and it's too slow...i can't use 3g as tata isn't providing us with 3g services here in our village...I'm very disappointed with tata docomo because it's speed when compared to other service providers, is miserably slow...I've tried contacting customer care but for no use...tata itself has provided with better speed some time ago but now they're just cheating customers with vulnerable services
