Mahanagar Telephone Nigam [MTNL] — wifi speed slow and no change in plan made.

Address:	vashi, Mumbai City, Maharashtra, 400703
Website:	mtnlmumbai.in

I have been requesting them so many times lodged complaint to mtnl about my plan change but they just say they will do today itself but nothing happens. I have rs 800 6 mbps plan but i get hardly 1 mbps so i told them to change to 8 mbps or 10 mbps but they are doing nothing. How many times should i have to call them and ask them to do it. I cannot even play youtube videos properly. They are just saying they will do it till evening and this and that but they do not do anything. Please help
