I had a call from a number ( 02046519784 ) saying my sim is going to be deactivated. They couldn't verify themselves; they stated that I'd receive a text.. which I didn't, and still haven't.

I will be going on holiday tomorrow and so although I do not belive this to be my network, as it would be a scam of some sort, I cannot have my sim deactivated, as it would leave me stranded without a way to navigate, get home or call for help.

And so, please can someone who is able to verify themselves using the code; '{ REMOVED }' call me to discuss this incident further.
