Get rid of MTNL. this is the best advise I can give you. MTNL connection comes with good luck or bad luck, who have good luck they enjoy their services at fullest and those who have bad luck are like you, who will never enjoy the services after repeated complaints. Because they have stupid customer services, no one is bothered if customer is having problem.
But still if you love MTNL, then raise the concern with nodal officer and provide all the complaint number, if nodal officer is not able to help you then contact the appellate authority. I am sure your problem should be resolved by then. Best of Luck....
Yes and No.
Yes becoz, everyone knows getting anyhelp from MTNL is like milking some elephant and also at ur location u can definitely get better ISPs with somewhat similar if not better plans.
No becoz most of the friends i know in delhi with MTNL have almost 95-98 % uptime with good speed.
I didn't use any download manager i downloaded from over 100 sites but still i get 5-15kbps
Even torrents give me same speed
Mean while u can try some download manager & see if it improves ur speed a bit or not. Try this -
