This company is International Client Services which work for a collection company.  Evidently 3 years ago a girl friend of my sons used us as a reference to get some kind of payday loan?  They have called repeatedly and we have informed them of the circumstances and each time they say they would take out our phone number.  Today was the last straw when they called and my husband was sleeping, he has been sick.  He accidently answered the phone and didnt know it, so when I picked up the phone to check the number I heard a voice saying "Why are you just breathing into the phone" very nasty.  This set me off and I admit I said a few choice words.  Anyway she said she would not take me off the list.  Tried to file something with the better business bureau, Company name not known.  Beware, even if your not who they think you are, it must be their duty to make your life difficult.
