I'm asking this question on behalf of my mother. Apologies if this is the wrong SO network, but it feels like the closest one to me.
A few months ago she received a letter through the post from eBay that confirmed someone had correctly registered an eBay Shop at her address. It was someone else's name, but her address. It felt sure like a scam to me, but I couldn't tell what it was (no premium rate numbers, no links, etc.). So my mother contacted eBay via their website and was told it was a simple mistake on the address the seller meant "Road" not "Avenue", and eBay corrected the problem. At the time we took this excuse, but in retrospect, it doesn't smell right now (e.g. the wrong road, but correct postcode?).
A few weeks ago, she received a number of SIM cards through the post, addressed to the same name as the person who setup the eBay company. She contacted the company that sent them, and they confirmed it was probably some sort of scam, trying to use my mother's address for their business, so that when the don't pay the bills, the debt collectors come knocking at the wrong house, but not much more help.
Is anyone aware of a scam like this (my google-fu turned up nothing)?
Does anyone know of any measures she can take to protect herself or authorities that should be contacted?
