A collections agency just called on a card I have not seen or heard from in years. They are requesting $560 or at least $150 by the end of this month. They will accept nothing less and will refuse payment send back anything less than $150. I explained that they just contacted me today and I have not had time to explore the validity of this debt and questioned why they were unwilling to explore a reasonable payment plan. They informed me that if I do not give them an answer by tomorrow afternoon they would start legal proceedings. Is this legal? Can they call after 5 years and give me 1 days notice? Can they demand an amount that I cannot pay at this time? I suggested that a payment of $50 - $75 would be more reasonable with possibly more in the future as I reconfigure my budget. They said $150 and nothing less. Do I have any options?
