M&M Sweets leaves a sour taste.

Holy Moley! Looks like I'll be in need of some legal services in the near future.
My duplex apartment is above a store front property and whoever runs the store downstairs is legally my landlord. I signed a one year lease agreement back in June 2005, for $1,100 per month with a $1,850 security deposit. A year later, this past June, they raised the rent to $1,300. No problem, I was expecting that.
Now, just yesterday, I get a call from the owner of the building, informing me that M&M Sweets, the franchise owners of the Tasti-D-Lite, my landlord, is evicted. This was due to the fact that M&M Sweets, a couple of fellows by the names of Mark and Mike, owe him over $3,000 and to top it all off, THEY HAVE MY SECURITY DEPOSIT.
That's $1,850 that's due me.
I saw them the other month, taking out some equipment and it looked like they were closing down.
I asked them, "Hey, are you guys moving out?" Mike responded with, "No, No, we're just closing it for the season."
Sounded fair enough, they were after all, an ice cream shop and nobody wants to eat ice cream when it's -5 outside.
But now, I feel betrayed, lied to, bamboozled, led astray.
Tasti-D-Lite has my money!
So what to do now... First off, I'm informing my legal representation service. Once I have them in place, then I'll make the call to Mike and Mark. They know what they did, and there's no rush for me to call them right now. When things are in place, then I'll start to put the heat on.
