I constantly get calls for a person who apparently used to have our number.  Each time I ask to be taken off of their mailing list.  Today I asked who she was and what company.  "Crystal Vega from DCS."  I asked what DCS was and what they do and she refused to answer.  I called back after she hung up and it went to an automated receiver for DCS and then directly to Ms. Vega's voicemail.

i thought it was bcs?? what is bcs??

They are DCS a collection company collecting a student loan. Typical collection agency tactics. Rudeness. Intimidation. Threatening Lawsuit, Wage Garnishment, the whole bit.
