I ordered 3 products on august 11, 2018. Next day 12 august 2018 they updated the status that the products got delivered with invoice with my fake signature.
I have not received my order yet and i am struggling with it for two days.
They have mailed me the receipt with fake signature without providing even contact of the delivery person.
in this case shadowfax is the delivery partner. nowhere do they provide their delivery agent contacts. i have not even got such text or mail that my product got delivered yet they have provided the invoice with some other person sign made. i can provide the original sign of mine with a original proof.
