Collect Pros review: sent a collection letter for something I never purchased. I do not even know what this is about.

I received a letter from a collec Pro dating this is an attempt to close your account. they want $34.94 for a product elite coupon deals and I have no idea what this is. I tried contacting the collect pros and cannot talk to anybody and I can't even find a phone number for elite coupon deals. I don't want my credit to be affected for this issue but I am NOT going to pay it! I did not purchase anything or use this elite coupon deals company in November of 2014 that they are stating I did. If I do not pay by May 3rd they are going to charge me 20 extra dollars. I'm not paying for something I don't even know what it is and I did not purchase or use. for some reason I am unable to upload a picture of the letter it is stating it is too large but if you need a copy I have it.
Thank you,
Susannah Simmons
