 it was a promo that i brought. one time and paid for. never agian received a letter stating that i had a past due balance until i received this letter from a collector stating i owed 197.72. This company DAR Waterfront & Associates is trying to collect a past due amount from a creditor company called EyeVibe in the amount of $98.71. It says I can make a secure payment online at their website or make a payment by phone but the phone number or mail in a payment to the address provided. When I called the phone number I could get a hold of no actual physical person and I have never in my life heard of a company or had any purchase with a company called EyeVibe. I believe this is a scandal to get peoples money. 

I called the number (1-800-289-5916) on the letter and the recording said I could only dispute in writing by sending a letter to:

DAR Waterfront & Associates 13547 Ventura Blvd., Suite 350  Sherman Oaks, CA 91423

or by going to darwaterfront.com/dispute and when I go to that website I get: NOT FOUND
