I was able to inquire the status of my DD via email.
First, I emailed the customer support and raised my concern.
The reponse was to coordinate directly to the branch.
But instead, i asked the support for the email of my branch.
Once it was provided, I emailed the branch (it's their business manager.)
After 3 days, I got the response by the branch.
I then realized base on the email, it took time for them to reply because the BM needs to confirm your information in their branch and email their head office to request the negotiation date.
I hope this will also work for you.
