I receive XXXX to XXXX calls per day from this company in a day - they are a collection agency - NCO Group - I have asked repeatedly to put everything in writing - and still have yet to receive any documentation. The calls start early morning and last till late at night, XXXX through XXXX. 
When I block the number they are calling from - they move on to another number. I have received voice mails stating that they are needing for me to return the call concerning a legal matter or I am being notified of legal action being taken.
