Update to my post.  I called several time and finally got in touch with Vanessa.  I explained to her that I did not purchase and asked is she had proof of delivery.  She stated it was sent US Postal mail and not signature was required.  I told her that I have not placed an order in years and would not pay this bill.  She then told me I would get a court dat in the mail in about 2 to 3 weeks and that I could contest.  While it is being contested, I would accumulate late fees and also attorney fees and that it could take up to 1 1/2 years in the courts to contest.  
We shall see what happens.

I am so glad I did an internet search for Disadvantages Workers of America and found this site.  I too had purchased items in the past and just yesterday, May 15, 2012 received a message on my home phone stating that I needed to call Vanessa regarding my account to avoid it being turned over to a collections agency and going to court.  When I called back she stated she was a supervisor and that they had tried to contact me several times but their collectors are not able to leave a message because of privacy laws.  Funny, their collectors aren't allowed to leave a message but as a Supervisor, she is allowed to leave a very detailed message.  I told her I would need to check this out as I couldn't remember purchasing from them lately.  I supposedly purchased lightbulbs from them in December 2010 at the cost of $89.99 and that I owed $377.99 - 18 months of late fees at $16 per month.  This is totally crazy.  I will be calling her back today and so glad I have this additional information.

I have just received a call from this telephone number "Workers of America" on my CID. The lady had called earlier & left a message that If I didn't call back she would pass my "Bill" onto a debt collection agency. I have no record of making the purchase she has on record. I did order items through Disadvantaged Workers of America many years ago but stopped because I had accumulated more than I needed. I also requested over & over again to have my name removed from their calling list to discover after a while that they just passed my name on to another similar organization eg Handicapped something or other. On one occasion the caller(a man) verbally abused me and I hung up. Oh! When I asked the amount of the supposed bill I was informed that it was in excess of $400.00 - due to late fees and interest payments. I refused categorically to pay. I was also told that the outfit seeking payment had phoned me repeatedly but were not allowed to leave voice mail messages! I asked what was wrong with the Postal Service to which she had no answer

I received a phone call from 562-334-0196 who identified herself as Jodi Chandler from the Internal Collection Department.  She said that I was on the list for ordering 2 tablecloths back in 2010.  The original price was $89.00, but that since Disadvantaged Workers had been unable to get a hold of me since, that the price was now 281 dollars and change...I told her that I have never ordered tablecloths and have not ordered anything since 2008.  She said that this was a courtesy call and the information would be turned over to attorneys and I would be given a court date if I did not pay.  I was furious and threatened to call the BBB. I asked for the name of her supervisor and she told me that her supervisor would tell me the same thing...I did not pay.
In the past, I also have had the Disadvantaged Worker call me real friendly like until I told him I was no longer ordering from them.  He started yelling, told me he had my information and would order for me.  I hung up.  He called back and told me since I was mean, he would order $500 worth of fire extinguishers
in my name and I could not do anything about it.  I put a flag on my debit card, but nothing happened.
