Can I just confirm if your family in Spain, are calling you from a landline or mobile number?
If you have not blocked their number coming through, are you able to ask a family member who has spoken to your family in Spain if they can check they have not blocked your number from there end in error?
We're just trying to eliminate, why you're unable to be called.
Can we ask if your relatives are calling you on your mobile or landline?
We may be best popping you over a private message so we can check your line and to make sure there are no faults. If you happy for me to do this, please click on the purple envelope to accept the chat.
