Pickrr — Product was delivered to some other guy,I didnt receive it

I didn't receive my order.The delivery guy gave it to some other person.I asked my neighbours as well.They haven't kept it.I have asked that person to give it to the security but he gave it to some random guy.
It's not even my fault.I have been ordering things for last 4 years, never had to complain about anything.Kindly look into my issue and I want my refund back
