Can we get some traction on this SR?

What has been happening (with a LOT of my SR's lately):

NTS replies with "can I come into a chat now"

I reply that I cannot, but I give dates and times that we CAN

Then I never hear anything for a week and then the NTS folks send the same reply:

"can I come into the chat now"

I realize that the date/timezone in India can cause some timing problems but they need to realize that we cannot necessarily just drop everything the minute we get an email to "step into a chat".

They ALSO need to realize that when we give dates and times for the next few days that we CAN coordinate something to at least reply instead of getting the silent treatment
