Le site zipmobiles.co.uk est-il sûr ?

This is a site which advertises mobile phones and spares. It is a very plausible and quite well made site. I ordered some items in February 2015. My money was taken but nothing arrived. After several weeks I tried to contact the seller. The site gives: a mobile number which returns "number not recognised" from BT; an email address which does not reply; and the "address" which is shown as a smart shop on the site is actually a run-down terraced house. Someone has gone to considerable trouble to set up the site and is pocketing money from orders which it has no intention of fulfilling. I got my money back from my credit card company who will write the money off. So it goes on!
