Who called from 4257138282

I got the call from 011 4257138282 but they don't talk they just hang up after a while

When you return the call, it does not ring, it disconnects. Wow what a reputable company that is.

received multiple calls from this number and didn't answer, no message, finally answered and they/it hung up.

Constantly calls and they do not leave a message. Can't find any information about the company but wonder how did they get my number. Will file a report with the Do Not Call List, probably will not do any good. Been getting all sorts of calls from unknown numbers, as of last count there were over 50 unknown numbers calling my phone.

this number keeps calling me. why?
