Avril says she is constantly flooded with the scammers, on her mobile number, and keeps blacking their numbers. Thing is, they never ring back on the same spoofed number, so why bother? Me, I only rarely get them on the mobile, but those who are brave enough, get a barrage of abuse from me - which seems to work. Landline, blocks all unknown caller numbers, unless they are willing to press a certain key, and record their name - which almost never happens, unless the caller is genuine. Hospitals, docs, police etc., are used to these call blockers, and do as requested, to get through - never any issue. The rest are blocked, and just show up in the list of missed callers.
