Swiggy — didn't get delivery still says order delivered

Address:

Mumbai City, Maharashtra

I have order one pastry, by mistake i have putted incomplete address, still they have accepted order and debited money as well. at the time of delivery they are complaining your address is not right, I strongly want to understand while accepting order why they don't verify whether this address is reachable or not / valid/ incomplete or incomplete, without any validation randomly accept it and not ready to refund.
if they get wrong address how could they send me the receipt with successful delivery .
