Just Energy collection department. Got a phone call from them about a past due payment from a year ago. First time I am hearing about a past due bill from them.

Received a call from 312-423-7313. Let it go to voicemail. Automated vm requested a return call about my account. I haven't had an account with them in over 5 years. I can't be in collections with them because i just bought a house about 6 weeks ago and it was/is not listed on my credit report. This company can take a hike. I just blocked the number.
