A man called and left voice mail asking for me by name. He spoke very fast and it was hard to understand what he said his name is ("Kyle Jones" or something like that). He gave the callback number 1-888-400-7804, but his called ID number showed 1-716-580-6110, which made me suspicious. He also left an extension number and a reference number. I have not returned his call.

This number is really FRAUD company ! they called also saying we are debit collect company ... so if you get a call from this number watch out

Lannie Mark @ 1-888-400-7804 ext.#2260 wanted a call back for a "financial matter".............I didn't return the call.

Someone from the number 888-400-7804 Called my business left a message for a phillis Baldwin. I have no clue who that is. They don't even say who they are with.

I keep getting calls from this number,I tell them I don't know who the person is and please remove my no from their list,they say they are ACI collection agency I do not own any money to any one.I spoke to Agirl named Christine

I KEEP GETTING CALLS FROM THIS PHONE NUMBER, ASKING FOR SOMEONE ELSE.  PLEASE STOP CALLING MY PHONE.  THE PERSON YOU ARE ASKING FOR, DOES NOT OWN THIS NUMBER.
