Who called from 5080123456

I get calls from this number, by the time I get to pick the phone up they hang up.  Just wondering who it is that is calling.

I get the same calls... no answer when I pick up.. They call multiple times in a row.

i get the same kind of calls, very strange, highly irritating >:[

oh and if you look at the number you'll notice it goes in numerical sequence which usually means spam...
0123456 it counts up from zero to six! how strange is that

This number is harrassing me and I will call the cops if the calls do not stop.
