DTDC Courier & Cargo — delayed delivery for 7x[protected]

The parcel that was scheduled for delivery on the 9th has still not been delivered. Could you please escalate this matter or forward it to higher management? Additionally, will your team take responsibility if the parcel is damaged or its contents become stale? I kindly request a discount voucher or a refund as compensation for the delay.

Additionally, I am writing emails to the customer support everyday and there's hardly a reply back.

A delivery is being scheduled, but by night I receive a message stating that the area is not serviceable. Despite reaching out via calls and emails, the issue is not being addressed seriously.
