I had past experience with calls re the debt of someone who lived at my address some 20 years ago and another with the same name except the middle initial and it took and FTC complaint to stop them. I received calls in XXXX 2015 from Enhanced Recovery re Debt Collection. 
One call referred to a letter which I assume was a validation letter sent to whomever owes whatever they are trying to collect. I wrote them a detailed letter on XXXX XXXX, 2015 ( cert. return rcpt ) telling them : 1. contact the person you wrote to, its not me. 
2. There is no reason for a debt collector to be contacting me. 
3. cease and desist. 
4. Further I am XXXX and do n't do business over the phone. 
5. I have a health condition that XXXX ( XXXX and XXXX XXXX ). 
6. their contacts did not appear to comply with the FPDCA 7. I looked forward to never hearing from them again. 
I thought it worked until Fri XXXX when I got the following msg on my answering machine : " this is a debt collection call from Enhanced Recovery please call XXXX ref XXXX. '' no identification as to the caller or what the debt is about ( not that I care ). 

All I want them to do is leave me alone. I sent a letter today reiterating the comments in the XXXX XXXX letter and telling them I would file a complaint. 

I will not call them back based on my past experience with another highly unethical collector and my XXXX. 
I know of no reason they should be calling me. I have not cosigned for anyone nor acted as executor of any estate. 

This company has not been abusive and until yesterday I thought the matter resolved. I will grant that my past horrible experience affects how I view this. 

I do believe that companies should be prohibited from contacting anyone just because they have a similar name or without at least stating we are contacting you in regard to a debt owed to XXXX by XXXX. 

I would like to think that this latest call is a result of a failure to communicate that no one should be calling.
