I received this notification and I have no idea who this company is. It states original creditor is XXXX. My last contact with XXXX was XX/XX/XXXX. I was receiving calls from an unknown caller and I blocked the number because of repeated calls. I received a message via voicemail and the caller stated that this call is for XXXX ( which is my name ). When stating his/her name and the name of the company the voice sound was muzzled and incomprehensible. I do n't owe this company and my attempt to notify them in writing ( with return receipt ) will be unsuccessful because they did n't provide me with a physical address - they provided a P.O. Box. Please help me if you can. Thank you in advance and I look forward to hearing from you. 

Sincerely,
