I'd like to chime in. A family member took a reliance pre-paid phone in feb 2003 or so. The person found out that they could make std calls all over India. So they did. Reliance said that std and isd is barred so the person though this was intentional from reliance's part that std was allowed.3 months later, reliance sent a bill for some 6000 Rs. 5000 odd of that was std calls. After the family member refused to pay the bill, service became sporadic. I think 1 year after that, the family member surrendered the phone and paid some or all of the dues(I'm not really sure of this) and ended all the misery that came with the reliance landline.Either way, if data transfer was not free under that reliance plan, he should have monitored his usage.Let me add my case too, sometime in oct or nov or 2002, the 2nd landline in my house that I used for internet came with a bill for 15000 odd Rs. Since I was used to heavy internet usage, the figure was correct. Before this bill, my father was very reluctant about cable internet(the only thing available in my area), but after that bill, the very next month I got a cable internet connection. 🙂My father eventually closed this landline and cleared the bill by feb or march 03.If I was really nuts about surfing the net and had no cable or dsl internet availability, I would get a hutch number, activate gprs. With my uncle's phone, I got a steady 43kbps and good ping. The only thing I'm not sure of is the amount of data transfer allowed. I think the max is 500MB/month, there might be unlimited plans too but I'm not sure.As for your question, does he have any proof that he did not surf more than 800MB? I have a d/l meter that tracks the amount of data transfer per day. If you are going to consumer court, you need to have something to support your statements and prove reliance was wrong.Pretty much, customers of all isp's except bsnl and exatt have dreamed/contemplated dragging their isp's to court for the service they provide/used to provide.
