Yes I do face same problem. In fact its been going on sporadically for many months now. But nothing like today.
If you see my post above (#947), same thing happened on 22nd June but the guy at their Delhi office (Mr. Rawat) insisted that my internet was at fault - and told me that rkglobal.net is loading alright on his internet.
I spent time in checking everything from anti-virus, firewall, odin registry, re-booting etc. But it turned out to be that their server was down.
This kind of out-right lying on part of broker is definitely not worth Rs. 9/- brokerage... Everything connected with R K Global is down on internet - their website, their Odin server till the time of this posting... hope they are not playing cricket with Dhoni!
