There was a boiler room telemarketing operation selling vacation time shares in my office building for three months. When they were evicted for non-payment of rent--they packed up and moved over the Thanksgiving weekend--they left mounds of garbage, including rotting food (about 30-40 large garbage bags full), a carpet full of ground out cigarettes, urine, feces and vomit, crack pipes, an unpaid $9,000 phone bill (mistakenly sent to my office)--and, just for fun, they stopped up a sink in one of the bathrooms and turned the water on full force, flooding that floor's hallways and flooding into a furniture store on the floor below, causing thousands of dollars of damage to their goods.
Tell me again how nice telemarketers are again.
And did they even pay their workers? A local operation, it turns out, did not pay their employees when they skipped town.
I'm not surprised. We used to do a web site for a "marketing research" agency who refused to pay for a major overhaul. We took the site down and took them to small claims court (we had a contract, signed by the president of the firm) and after many BS delays on their part, they paid most of what they owed us. We wrote the rest off as being a lesson in why not to deal with scumbags.
A year later I ran into the guy who they had contracted to re-do their site (they were too stupid to crawl our site to get the files before we took it down). Yup, you guessed it - they had refused to pay him too.
