It's not a scam. The "sister" that called me was not a scam. When it came to my credit card info I knew something was going on. I didn't give her any information and the transaction didn't come through.

A gentleman called my parents house and stated that his name was "Robert Johnson". When my mother asked what it was about he stated that if he did not deliver papers to my parents he would go to my home. My parents told him to stop by and that they would take the information he had in the voicemail; in the mean time my mother called to call the number they called from; which stated they were a lawyer. My sister did as well, and spoke with a "Mr. Wright" whom she was also told was not a lawyer, but was an associate and was just trying to collect on an old debt that he stated was not legally collectable on. We were told by her that once it is legally collectable they could garnish my mother's wages. My parents have reported this to the local sheriffs office. I have blocked the number on my phone.

I have gotten a few calls from this number. I keep rejecting them, but they keep calling. They just left me a voice mail. I called it back from a landline, but "the mailbox is full."

The number shows up as "CADILLAC" on caller ID. When I picked up they asked for me and would get rude when I answered. Told them they have the wrong number. T-mobile has to block them! It's very annoying! If you call the number back the automated service will say "thank you for calling TD Canada Trust"

This company claims to help seniors. This company is a scam. They claim that seniors with knee, back, or shoulder issues have $1000 for a Medicare supplement. They will try to get you to pay for a "package" that was either $9.95, $9.96 or $100 (yes that's correct it is $100) it's up to the patient decide if they want it deducted from their account or if they don't want it deducted at all. It's a scam. DO NOT FALL FOR THIS SCAM!!!!!

Same with me as the caller who called at 11:15 a.m. this morning using a different name calling about 2-3 times every day. Never leaves a message and has called several times over the past 3-4 months. Very annoying indeed!

got the call today, just received another one but ignored it to be safe. i am also at work and it only rang once but it really started as i was talking to someone else. i have to pay for each call, so i called back thinking it was something important. i got something like this (same as above) some prerecorded message about medical insurance. i hung up as i was trying to get more info. called back, hit 9 to add yourself to their "do not call list". now i am hoping that does the trick.

They are at it again - they called and left a message but it was an automated response, not any live person. Said I would be arrested if I did not call back. They are still making the rounds

Got a call from this number from a gentleman I could barely understand with very poor english. Told me that it is not a "personal matter" and I know that if it is it most likely someone I know. If it is someones personal business they must have information already. He said he will bring to court papers today and that it will be a "garnishment." I didn't listen to any further. The next time they call I am going to ask for the address for them to send them legal paperwork so that I can put them away for harassment and scamming.
