I have been using tatadocomo from last one and a half year.I am constantly facing a problem of zero signals or minimum signals,but this problem has not been solved till date even after complaining for so many times.they just give me alternatives which are not even working.It seems like they just don't want to work.If they cannot handle it then why they are pretending to be a very good service provider.If they cannot solve a problem for such a long time then they are totally inefficient.now i have decided to write online comlaint because from last 4 days i am not getting even the minimum signal that means zero signals,and i have given complaint also but till now nothing has been done.please look into the matter.
