Who called from 2081850553

I had 4 phone calls from this number. Don't know who and why it's calling me from USA

I've had 6 calls from this number in the last 24 hours. Finally answered it on the fifth time, total silence, so hung up. The number then immediately called again.  No idea who it is, have added it to the ever increasing list of numbers under Do Not Answer in my contacts list.

Ditto above - my wife has received a number of calls from this number. We do not recognise it and have not answered it.

We have received 4 phonecalls to our home line and mobile in the last half an hour silence when you pick up have no idea who or why they are calling

Received a missed call from that number didn't want to return a call when i wasn't sure who it was from.
