<prompt> Human: Last year I tried working sales. I hated it, hated what I was selling, so I went to my boss and spoke with her telling her it wasnt a good fit for me and I wouldnt be able to keep working there. I told her this in the first week of January but I didnt hand in a letter of resignation, but I do have texted from her after that asking me to come back to work in February I believe, Id have to check. We had a ledger that kept track of our commissions, and money we owed to the company if we decided to participate in events. When I quit I had a positive balance in my ledger and never got a check for it. I didnt pursue anything with it because it was only a small amount and I just wanted to be done with the company. The other day I received a certified letter in the mail, saying I owe them 2k and if I didnt pay by a certain date they would send it to collections. The letter is post marked the day they said I had to make payment by. Ive never been in a situation like this before and I dont know where to start, kind of freaking out. I currently have a credit score over 800, Ive never had anything go to collections, I dont have 2k right now. I dont know what to do, please if anyone can give me some advice I would really appreciate it. Tl;Dr former employer says I owe 2k for my negative ledger balance. When I quit my ledger balance was positive. The letter they sent about it didnt give me any time to pay before they sent it to collections. I dont know what to do.  <response>: They gave you 0 day buffer to pay back before collection? Ill warn all my ex-colleagues if thats how the company handle their business.
