Thanks for the suggestion guys..
Just did exactly the same. Asked the delivery guy if he could cancel the delivery from his side and he promptly did it.
I was worried because there were other items in the same order, which I didn't want to return and the delivery OTP was the same combinedly. So if I provided the OTP then it would mean I have received all of the items.
Luckily the delivery guy explained that it doesn't matter, just accept the items I wanted and he can mark the others to be cancelled.
And it reflected immediately in my order section. Also received a couple of calls too from amazon personnel asking confirmation whether I really refused delivery or not.
Overall pretty satisfied with how things went. Just waiting for the refund now
Thanks again to
@SunnyBoi for sharing the deal literally last minute for me
Now looking forward to putting that 80 plus gold rating to test and see what the fuss is all about..
