It is Client services. I think they high jack local phone numbers to fool you into answering.
And you are right. They call constantly. But who gives a f..k.

OMG.have been hounded for over 3 months non-stop by this compay Client Services, St Charles, Missouri, for someone named Sharon Renford Smith, who we have no idea who that is. We have picked up the automated calls and inicated that we are not this person but the calls just keep coming. Please something MUST be done about this company. We are at wits end. If I had time I would call them nonstop to show them how it feels. Surely this is illegal and litigation is pending. I need compensation for this severe aggrevation

Call immediately had me on hold with a recording that someone would be with me shortly.  Pushing several random buttons got a female (rather rude) who asked for Ronald Augustine.  I asked where they got the number, and she asked if I was Augustine.  When I said that I was not, she abruptly said "Okay, goodbye," and promptly hung up.  A call back to the number (203 is a CT area code and this exchange dialed as a local number to me in the Eastern Fairfield County area)got a voicemail at Client Services.

How I can stop to caal me 100 times a day?
