Who called from 21582054

same as below, junk call

same here, call back there is actual person claimed wrong number.
Won't admit any company name. They probably verify, collect actual mobile #, recorded onto annoying sales call.

Ringed once and hung-up!!!

Same thing, received several calls from this number at night time. I called back to see who called me and they did not even answer. Called back again and they were very rude, refusing to tell whom they were. I tried to call them again and again until I received an answer, and all I got is OVER 100 CALLS during the whole night from unknown number!!!!!
My advise: do not stop to call them, this bother them a lot as they have no choice but to answer.

I received it too, just ringed once and hang up.
Now I know what's happened.
CHEAP!
