Hi,I'm Zoey and I'll be assisting you. I'm reviewing your question now. Are you online at this time?
It is a good idea not to provide any sensitive information about yourself to any company that makes unsolicited contact with you and which you cannot verify.
These companies generally make unsolicited calls at random from lists that are computer generated or which they purchase. They only learn whether or not the lists are accurate if you respond. So long as you do not reply to them your personal data is not compromised.
I have left you an answer. If that was not what you needed to know, let me know.
I couldn't tell you one way or the other.
A reverse search tells me that it's a London landline, but it could be a computer generated number for a VOIP service such as Google phone or Skype, which would make more sense if you are not able to make calls to it.
All I can tell you is that it appears to be a robo caller and there are complaints about such calls coming from this number on the web. (see link)
This is a standard telemarketing ploy. If you didn't give then any information, nothing should happen except that they will likely call repeatedly.
If your phone carrier can block their calls, you ought to have the do so.
No need to apologize. But I do appreciate knowing that I did provide you with some useful assistance after all!
