You know honestly speaking - I completely understand the state everyone is, the whole process to get visa stretched a lot for some of us and it shouldn't have been this way!! But we can't do much about right? Just follow the process and wait for a revert, give them at least 2 days before you send a followup again. The system they have built is very manual and they have standard responses set, so don't expect personalized responses or acknowledgements. I have seen some people suggesting everyone to send them emails everyday - which I think will just put more burden on the system for you and for everyone else. No offence to anyone, but I feel sending a mail everyday is just not needed.
