Where can I find out if our number could be a duplicate. Just had a call and caller says that they got through to someone else who says they get lots of calls for my number.
Your 087 fresh phone number is a unique number and is not duplicated anywhere,
I see you have an active call divert set up on the service, diverting calls to you 082 mobile number, crossed lines or mal-routing could occur here, on the part of the mobile provider.
We unfortunately cannot trace it any further, I can only urge you to report this to the mobile service provider.
