I’ve been sent an SMS ostensibly from Correus (on +34 623 324 309) asking me to cough up 1.99€ due on a packet which you pay on line by clicking the link.  It’s a scam so don’t even click the link.  Just bar the caller.  Fortunately, being of a suspicious nature, I checked at the post office who confirmed they were aware of the scam before I took any action.
