Complete spam this company uses different ending numbers so you can’t block them that ring once and hang up. Then at 9 pm this person rings trying to sell bitcoin or something.

Saying there PayPal and moneys being taken from my account

called at 10 pm at night for the 4 the time today

Been calling for a few days now as late as 9.30 pm have called the number from my land line and end up with music (02) 8379 8096 and several different number with a change of last 3 digits ......
Very childish nuance calls....

I have had 4 calls today from this and similar numbers that ring for about 5 seconds and then stop. I am guessing it must be some sort of scam.
