Did not answer.  They did not leave a message.  I called back to see what the company name was then googled them.  Appears to be a debt collection agency.

Caller ID said: Client Services, Inc. I did not answer and they did not leave a message.

Have received repeated calls from this number. No voice messages. Caller ID says Client Svcs Inc.

Just calls leaves no messages

From the comments from other numbers this place uses, they are debt collectors!  Multiple numbers. Wouldn't be quite so bad if I owed anyone anything, but do not....again, from other posts, they are looking for some one else they think you know.  SCUM!
