jaison,
I use comstock datafeed through Quicken Quotes Live (qql.quicken.com) and there are no problems whatsoever with naz data feed today.
I suggest you ask for refund. But even if you get a refund, Qcharts will not likely honor it (at least it didn't mine). I had constant datafeed problems for many months with Qcharts(data lagging, servers down) until I switched to Nextrend and Quicken Quotes Live. What a difference - rocksolid datafeed. I haven't had such problems since.
