Complaint 75419 Details

I ordered one lens from them. They called for a credit card question. Started offering me better lenses at a good price. They offered a Sigma 70-300 F/4-5.6 autofocus pro lens. Sent me to a second site to verify it (assume one they created).
Called back 5 minutes later to cancel, was told 5:00 their time was the cut off and I was not able to cancel. I will have to call and get a return number and send it back for a credit.
Credit card says I have to go through the steps to dispute it and they have 15 days to credit my account, from the time of the return.
I tried calling back a number of times and continued to get "sorry too late". I also put it in writing by email in under 10 minutes after the order.
I called Sigma lenses today. All their lenses are professional level, but none are marked pro. If you web search the lens you will find the one without PRO listed, selling for between $160-220 not the $490 (with shipping insurance etc).

I am hopeful the return will go smoothly with a credit to my credit card, but others need to watch out for this site, high pressure, special deals, and not what they say they are selling.
