These emails aren't from these companies at all , they are just being used to make the email look more genuine, ie. from a real company.

Note

It's also worth remembering that the company itself may not have any knowledge of this email and it's link(s) or attachment as it won't have come from their servers and IT systems but from an external bot net.

It's not advised to ring them as there won't really be anything they can do to help you.
