I didn't answer because my phone service said "Warning: Suspicious Calling Pattern" - I rec'd another call the next day from a number starting with 02 7234 172 and I can see others have recently listed suspicious calls for numbers starting with those same 6 digits.

Caller: delusional idiot

some scamming fkwit wanting to know if i was interested in a car loan

I've had this number call several times, different times of the day and night. My phone comes up with "Warning Suspicious Calling Pattern". Never seen this notice on my phone before. Sure not going to answer it!!

Called and silence? Another nuisance call, these calls have certainly ramped up!
