Received a "robocall" from this number, stating that it was an attempt to locate me; stated to press "0" to speak to an "investigator". No other information was given.
800notes is not affiliated with your callers, we are not calling you either. 800notes is a forum for reporting who calls you and any information you may have about the call to share with other forum users. It is highly doubtful that your callers are reading here also. We can't stop anyone from calling you either or remove from a list.
Consider getting a call blocking device or phone.. You can google them and many are around $50.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.
Please see Alfalfa's post above. Debt collection doesn't fall under the DNC, it falls under the FDCPA laws.
