refers to an 866 number in voice message

Called at 6;47,8;04,and 9;58.  I am not answering because I have been getting harrassing phone calls from CCS and I think this is another number for them.  It's a credit agency.  I have had this number for 4 yrs but the guy who had it before me must have had really bad credit and he gave my number out.  I think he still is.  I don't know how to stop this.  I have told the ccs people that I don't know the guy but they were extremely rude and continue to call.

fellow named bill catlett called me looking for a neighbor of mine.  he left me his number 404.315.5118.  I reported this information to the FTC office in Washington D.C.  They don themselves as a multiple financial institution.

Called and asked my husband for me with my correct first name and then asked about a neighbor of mine.  My husband said he didn't know him and then the guy on the phone said thank you and hung up.

Is calling neighbors leaving messages for me to call them. I have no idea who they are but I believe calling neighbors is stepping way over the boundaries.
