Strange Call Claiming To Be EE - Is this genuine?

[DavidCannon]

I just received an odd phone call from an "EE guide"

The number was 07973 100 619.

He asked if all was good with the service then I was sent the 4 digit pin he then asked and I gave him it.

I gave no personal information, bank details or anything like that. Just the 4 digit code.

Was this a genuine EE call?

As I said, it just felt kinda odd.

Thank you - never thought about "marketing" settings so that's really helpful to know who to speak to.
