As per my understanding, you should call them and ask them for your ECA status update.
my timeline:
Applied: 04-05-2017
confirmation of receipt: 15-06-2017 (after emailing them and ask them about my ECA status update)
email of Certificate: 31 July 2017 after calling them again about my status however on the certificate it is stated that it has been granted on 12 July 2017.
I agree that the people on phone are very nice and helpful.
