Mr. Singh

Mr Singh is that name of the dude that calls me several times a month from a collection agency.  I have a pretty close relationship with Mr Singh.  I don't know anything about Mr Singh, but he sure as shit knows a lot about me.
I "met" Mr Singh about 2 1/2 years ago when I called the Amex customer service number after dealing with their fraudulent charges dept.  My amex had been used without my consent, and wracked up $22,000  in charges in January of 2008. Obviously, I was a victim of identity theft.... oh wait, no. I was a victim of my husband, again.
After many months of many lies, I learned that my (soon to be) ex had taken my amex, hawked my engagement ring, and flown to Vegas and spent $22,000 "trying to win" enough money to pay back the mob dudes that he had borrowed money from in 2005 .
Which brings us back to Mr Singh.  This is the guy that was assigned to my case.
I mistakenly told Mr Singh that I thought I would be receiving a decent amount of money in November of 2010.. This was foolish, to say the least, to mention to Mr Singh.
Long story short, I did not receive said money, but boy, howdy does Mr Singh ask me about it weekly now.
"Hello jt?"  "yes. hi mr singh"  this is mr singh, i am calling from *(^)*(& collection agency. this is an attempt to collect a debt. this conversation may be recorded...... blah blah blah" 
I hate mr singh.  I talk to him like he's an ex-boyfriend who just can't let go--- "listen Mr Singh, I KNOW you want to settle this debt, so do I!!! but every time you call me, you are just making me feel bad!! you are a constant reminder of how bad things are. you are not making me want to help you. you are making me want to stop answering the phone, and ignore you more. do you understand, mr singh?  are you picking up what i'm putting down here? back off!"--- yes, this is seriously how i talk to this dude.
what do i care? he is making just above minimum wage at some firm in india, trying to work his way up to manager of customer service reps.  me, i'm just trying to hold it together.
