Forgot to post this here. Received call from "+3104" on 30th October. Obviously never answered it - I only ever answer identifiable numbers that i've attached a name to. However, this caller number appears to be different and more sinister from the usual more 'normal' spam or scam numbers.

Called again today by this number. Didn't answer. Was interested to see I last reported this number a month ago. Reporting this number to Ofcom as TPS registered.

its iforex call centre no.

Have received 2 calls in the past 2 days, missed by chance and would also be missed by choice if I had phone with me. 3104? With no message, really? Obviously whomever/whatever it is they are after will take a while for them to get/sell...pass

Its telus. (A phone service 4 net)
