Rude and continued to talk over me while explaining that I was at work and would not discuss the matter. Continued talking then made rude comments that he isnt the one who didnt pay their bills and he didnt care about my issue. 

Each time I stated I was at work, he continued talking over me and was rude. I do not know how they even found my work number because I do not write it down nor call it. 

In addition, I looked the number up and it was a personal phone number used not a business and I am concerned this person has my information and may not be secured. I did not verify any information except that the company in question refused my payments I was making when I was unemployed and had no money.
