Delhivery — Delayed delivery even after waiting for a week

Address:

2/B/1 KAMAR PARA LANE, BARANAGAR, NORTH 24 PARGANAS

I had ordered wireless earbuds from BoAt website on November 27th, 2022 and it was showing to be delivered after a week, by December 4th, 2022. Where electronic items are delivered within 1-2 days of order by Flipkart/Amazon with good enough offers, I was given a week later estimated delivery date by Delhivery. Still I have been okay with it as at least it was to be delivered before the occasion I ordered the product for.
But on the last days of delivery, when the parcel had already reached Dankuni (near my delivery address), it gets dispatched to Punjab.
And now the delivery is showing further 2 days delayed. So what exactly will I do with the product if it's delivered after the occasion which I ordered the product for? Their stupid errors, unprofessional and unethical behaviour cause huge problems to customers.
