Who called from 2345

Have had several calls form this number, spoke to a male with a foreign accent. Said it was PPI claims...I told them where to get off

called 19 times one day - called at 4am last night

received a call from 2345.  no response when I answered, it just hung up.

I just got a call from this number which I ignored.  No VM.  Shortly after I received an email from sellersupport.amazon.co.uk which stated that they'd attempted to call.  This would've been a legitimate call, in this case, had I not been suspicious of the incoming number.

This number calls me often.  When I pick up an asian man answers and asks for me by name.  I tell him every time that he has reached the wrong number (in case he's a bill collector) and he hangs up on me.
