Have received 2 calls from this number on 26th & 28th at different times of day. No background sound, but when I answered hello, they hung up immediately

Kept trying to ask for my name a number of times. The line was quite static-ee and could only pick up scant details. Indian or Srilankan accent.

I rang back the number (08) 7160 3477, spoke with someone who hung up right away

As per usual no background sound when i answered silently but listening.. then i said hello, &they hung up immediately. Another robot scam number never exists either!
