NUH (private) Glucose Test

I did the glucose test today and the clinic (women's clinic Ruby) informed that they will update the results by end day. It is already end day and I have yet to receive any calls. Anyone experienced the same? Saw the results on the app but it doesn't indicate if I have or do not have gestational diabetes. Tried calling the main hotline also and they are not helpful at all and are unable to transfer me to the clinic. Anyone experienced the same as well? Thank you.
