NO, what the collector did to you is NOT legal. While you do have to follow up by letter, you can tell them to "stop playing on your phone" (stop calling you) verbally. Calling everyone and their neighbor with the message "Tell her to call us back.", when they
know where you are and can contact you directly, is also not legal.
The first thing you must do, as Pyran would say, is "Stay Off The Phone!" Unless you can record the conversation...and are in a position to control it. You are not at this time--CAs are stupid, but they, like animals, do sense fear, and take advantage of it. If they want to contact you by phone anyway, until they get the letter, they can leave those "poison" messages on the answering machine or voice mail. And, SAVE those messages! Great evidence in court. Should you have to go there
Next, send a validation of debt letter with what used to be called a "Limited C&D", but is better referred to as the "Inconvenience clause"; this makes it clear that you find that their calls are always, eh, "inconvenient". Send the letter CMRRR (certified mail, return receipt requested). They can contact you by mail...a necessity so that they are not prompted to sue you because they cannot contact you otherwise. Don't say or do anything to "admit" to the
alleged debt...please! They haven't proven the thing exists, or that it's yours...so why entrap yourself?
If they contact you anyway, without validating first, and make fools of themselves trying to collect, (or, even if they do validate, and
still make fools of themselves) you can always sue them.
Broke Chica is absolutely correct with this entire post. I believe they can only contact you 3 times a week within limited hours too. If they continue to call you and you have the messages saved it could really help you build a case against them for violating your rights. You need to sent them a good DV letter tommorrow with a limited C & D. Once they recieve the C & D, game on. But you have to keep a copy of the letter and send it CMRRR, so you can prove they got it. Just like the chica said.
