Hello,I am using monsoon offer plan of tata which offers me 256 kbps wherein at night 8pm to 8 am its free for downloading. And in daytime it charges me 50 paise per mb. I just checked my internet usage and i was shocked to what i seen.On date 16/3/08 it says i downloaded 841.7 mb and uploaded 708.14 mb in day time. This is absolute lie, in actual fact i downloaded and uploaded all this data in night time when its free for me. And its obvious they will charge me almost 800 rs more to me in the bill because of their wrong calculation.Suggest me, what i as a customer can do in this matter as i have no tools to prove that they did wrong calculations. I am helpless.I sent the mail to CC just now, waiting for there reply.Your suggestions would be much appreciated.Thank-you
