Well, Airtel Delhi disconnects the STD calls after every 90 mins. This is a verified number that I have seen n number of times when I am on call. I don't know about the local calls.
But I really don't think that the professional calls last that long, that too regularly. I think we rarely talk that long for official purposes or to our parents. There is only one type of call that routinely extends that long and well a gesture is enough for the smart :p
Hi! I used MTNL for more than 4 years and one fine day they deducted 30Rs from my account for some downloading which I didn't do.I complained it to CC and they didn't give me proper response.But in their site,they updated as my problem is solved.Then after a week or so, again thrice 30Rs and one time 10Rs deducted from my account that too within 5 Minutes all happened.Again I called up the CC.For this also,before solving my problem,they updated in their site as my problem is solved.So finally I said ffuckk MTNL.
