<prompt> Human: Hi rpf,In February 2016 I moved from an apartment complex into a house. Less than a week after moving out, while still in the hustle and bustle of moving. I received a notification that I owed 175 to my apartment complex for advanced carpet cleaning. While I acknowledged this, it was a very busy time, and I completely forgot about this letter.Fast forward 12 months, hadnt received any sort of notification phone call, email, letter from my old apartment complex.Yesterday I received a letter from a collection agency saying I owed 175, On behalf of the my old apartment complex. Can I actually dispute this on the grounds that there was next-to no communication from the old apartment complex regarding the amount I owed them aside from a letter that was sent to me less than a week after I moved out?I try hard to keep my credit in check, and if I would have received a phone call or another letter especially when the business of moving calmed down I would have most definitely paid my debt to them.  <response>: You were sent a bill a year ago, and you ignored it. How many communication is enough to you?
