Who called from 6478461221

Received two called in less than 2 days. One call was listed as 64 7 846 1221 from Hamilton, Waikato New Zealand and the other one as 647-846-1221 from Ontario. Since I don't know anyone in New Zealand, I didn't pick up. I'm pretty sure it's spam and they messed up their call number.

It's ARO Inc., a collection agency. They also use (844) 528-0423

Same call no answer

They said it was Air Canada and that I won a trip. Called me twice in 1 week so far.

missed call from this number
