I called back number (02) 8004 5068 and No one pick up
I think it a scam

Caller: Said they were (Michael) from Thai Airways - something about a Phuket Holiday promotion

Told him politely I wasn't interested and to please take my number off their call list.
Not 2 minutes later he called back - same tone and speel. Wasn't as polite the second time. Have since blocked the number

I picked up a call from (02) 8004 5068. Nothing but silence from the other end. I called back and the call was picked up... again, completely silent on the other end. Will block.

I called back number (02) 8004 5068 reached voice mail but did not hear the name of the company properly.
