It is a scam. Someone else has used your name and address to order items with a stolen / cloned card. Once the items have been delivered the scamers will ring / email you, pretending to be from the company who provided the items, to say it was a mistake and they will come right round to collect the items.
You don't lose out, only the company who provide the items.
If it works once they will use the same card / name & address combination to order ever more expensive items.
When it happened to me it started with some fudge and flowers, moved onto a large shed and then 8 pairs of size 9 super-stilleto shoes usually worn by transvestites.
Ignore.
