Let me describe Docomo in simple words - Worst Service Provider, Worst Network, Worst Customer service.
I took a unlimited STD plan(Rs 899 /Month). When I got the bill I saw I was billed Rs 1304 and out of Rs 1304, Rs 600 was for Data Usage! I never asked them to provide me Data service and still they are billing me for that. This is just one incident. Lets not talk about their signal which is pathetic. And the customer service, God, they are even worse!
Docomo is just looting common Indian citizen.
