HI. 

I have recently moved from Vodafone to  Pay as you go, and then less than a week after I moved to Pay Monthly.

So in a nutshell, I have  Moved my number from VF to O2 PAG (new SIM Card), and then to O2 PM (new sim card again). When I was texting my Manager, she has advised me that my number come up different to the one I wanted to keep, but when I call both my husband numbers all seems to be correct. have you ever come across such an issue?

Confirmation from my LM, that she sees a different number 

Any help with this is very much appreciated
