Phone support unable to honor Dell warranty on peripherals with Best Buy receipt

Phone only support system is not allowing me to provide a receipt and start a warranty claim. I attempted three times to explain that I have a Dell mouse with a Dell Limited Hardware Warranty and a receipt from Best Buy. All three support agents were stumped by how to proceed without a Dell service tag or Dell order number. I believe that the phone agents wanted to assist, but do not know how to receive a receipt.

Devices Without Service Tag or Express Service Code

explains: "If you bought the device from a reseller or partner, just provide your original purchase receipt, and we'll assist you from there.". Unfortunately, Dell's phone only support system is not allowing me to provide the receipt.

I purchased the Dell MS900 from Best Buy on March 8, 2004 with a 3 year manufacturer's warranty and have the receipt. This mouse has a vertical scroll wheel that allows fast scrolling through long documents and web pages or notched scrolling for precision. The notched scrolling stopped working. This is a hardware malfunction that cannot be resolved over the phone. 

Please contact me to with how to submit my receipt and process the Dell product's replacement under its 3-year Advanced Exchange Service within its 3-year Limited Hardware Warranty.

Thank you
