Supr Daily — Issue with Delivery

Hi, I have subscribed for milk and have clearly instructed that the delivery should be done by 6.00 am.
It has been more the 3 months now but everyday milk gets delivered after 8.30 am.
Inspite of raising this complaint everyday no one from the supr team is bothered to resolve the issue.
Seems like they really don't care for customers.
Also the delivery person seems to figid with the milk as the quality has deteriorated from past few days.
