How to get rid of someone else's debt collector?
Sue the debt collectors in small claims court.   There are several example stories around the internet, but this is a well written one from the consumerist. If your phone is a cell phone: "it  is against the law for a company to  leave a pre-recorded message on your  cell phone." In fact, the call frequency increased   once they realized they had reached a   live person. I called each of these   companies multiple times, and though I   was given assurances each time that my   number would be taken off of their   lists, the calls continued, morning,   noon and night. At my wits end, I   decided the only way to have the   harassing calls stop was to file suits   against the collection companies. It's   very important to understand that it   is against the law for a company to   leave a pre-recorded message on your   cell phone. Armed with this knowledge,   I filed suit against several of the   collection companies. I filed in small   claims court so I did not need to hire   an attorney, and the process was as   simple as completing a paragraph on a   complaint form. For evidence, I had   over a hundred Google Voicemail   transcripts showing the times the   companies called and the text of the   pre-recorded messages. Mysteriously, the calls all stopped   immediately on the same date the   collection companies received the   certified letters stating they were   being sued. Then a new flurry of calls   began pouring in. This time it was   their attorneys. The attorneys representing these out   of state collection companies were all   desperate to settle out of court. hey   did not want to incur the expense of   traveling for court or hiring a local   law firm who wasn't on retainer. They   also understood they had no   justifiable defense for the calls. To   make a long story short, so far I have   successfully sued 3 of these   collection companies and settled for   more than $5,000 out of court. All it   cost me was $35 and 20 minutes per   suit. Making these companies pay is the only   incentive for them to stop their   illegal and harassing practices. If   more consumers knew their rights and   actually took a few minutes to stand   up for them, it would become less   profitable for these companies to   conduct business the way they do now. -Source And whether you have a cell phone or land line,  It is illegal for the debt collectors to tell you they are calling to collect a debt for someone else under the Fair Debt Collection Practices Act (wikipedia, ftc docs). What Remedies Are Available If The   Debt Collector Violates The Law Under   the Fair Debt Collection Practices   Act, you have the right to sue a debt   collector in state or federal court   within one year from the date of the   violation. If you win, you may recover   damages in the amount of any losses   you suffered as a result of the   violation, plus an additional amount   of up to $1,000.00. You may also be   able to recover court costs and   attorney fees. If the same debt collector has engaged   in unlawful conduct with a number of   consumers, it may be possible to find   a lawyer who will file a class action   lawsuit. -Source With regard to whether you can sue under FDCPA if you are not the debtor, one FDCPA lawyer (take with grain of salt) says yes: Did you know that it doesn't matter if   you owe the account the debt collector   is calling you about or not? If a debt   collector violates the FDCPA (the   federal Fair Debt Collection Practices   Act, 15 USC 1692 et. seq.) that debt   collector could be liable to pay you   statutory damages, actual damages,   attorney's fees, and court costs. -Source
