Who called from 2028705886

multiple calls throughout the day, no msg left on voicemail. callback gets a greeting of 'thank you for calling I C Systems.' They are a collection agency.

no message left, just annoying.  use call block.

When I called back - after holding for a while - they said this was IEC Systems....no doubt a bill collector.

I have received numerous calls from this number.  They keep asking for a person I have never heard of.   The last person who called was extremely rude.  When I called back the woman on the phone identified it as "IEC Enterprises" and refused to give any information.

I receive a call but no one responds on the other end - repeatedly throughout the day and evening.
