Arrestment on business phone line

SouthWest Recovery called yesterday. I work with sales people and he gave the same speech my sales guys use to get business. I gave him the email address for accounts receivable and said i could take his info but we already use another company. He proceeded to tell me that our company was looking for a credit manager and wanted to know who the person to speak with about the accounts would be. --- He gave me a bad vibe. I thanked him for his call and asked him to email me.

Said they are looking for tax money, gave me a badge number and everything...said I was going to be arrested if I don't call back! Seriously I wouldn't call them back

called my office at 6:50 AM! not looking for money from me, looking for me to hire them to collect for me... rediculous
