Cavalry Portfolio Services Continuous Phone Calls and Letters Tempe, Arizona

Cavalry Portfolio has been blowing my cell phone up for the past 6-8 months.  Beginning in December they started to call my work.  I've told the "lady" repeatedly that I do not have the funds to pay them.  I am barely getting by as it is.  The woman that called me even admitted that I'm over extended as it is.  I'm 26 years old.  I work full time and I was working on my second degree, but decided to take a semester off.  Unfortunately, Cavalry has yet to take a break on trying to get my money.  That would have to mean they have a soul.

So I ran my credit report to see what all this is about.  Turns out it is a Bank of America account that was closed and charged off.  The Bank of America account was delinquent  in July 2006 and charged off in September of 2009.  Cavalry reopened the account July 2007. 

I know the Tennessee Statute of Limitations is 6 years, but does this mean I have to keep enduring this harassment? It's so embarrassing when she calls me at work, but she won't stop!   LVNV FUNDING, LLC is also hounding me as well.  I could really use some advice, guidance, and help (all of the above).  Please someone...  Help.
