This was a sponsored link through Facebook. I clicked on that link and a new request form opened . It asked for my name and other personal details. I before that when I saw the sponsored link, I asked in the comments if they had cash on delivery. They did not reply so I came out of the link without completing the order. However yesterday I received an email stating that my order is etc., etc., and today I received another email to state that it's shipped. They are asking me to pay a huge amount for the products that I have not ordered (in the email there is an invoice). Today I sent an email and asked them to reverse the shipment and yet to receive a response from them. Tried to search for their contact number but in vain.
