Complaint Review: Sonic Cameras

I ordered camera lens on-line 2-14-2008 from Sonic Cameras. Salesman (Daniel) called next day to change credit card from AMEX to Mastercard. Salesman recommended I change the order from the Nikkor I wanted to a Sigma. Researched the Sigma (price $799 on Sonic, $150-200 elsewhere) & refused. Daniel became abusive & said he would charge my credit card a restocking fee for both lenses. Credit card company had been contacted by Sonic Camera for authorization. I canceled the card. Wish I had seen these posts before I started the Sonic Cameras experience!
