PowerSellerDigital Advertises one price, charges at another rate Snellville, GA Georgia

I bought a Canon camera on PowerSellerDigital online in mid-May.  In addition to the camera, the website announced a "Memorial Day" sale where certain other items came with it.  I decided to use this seller because the Canon camera price was $100 less than the price advertised on other websites.  I called and was told by some man that there would be a small charge for a battery. HE focused on the larger battery and I thought he was saying that the additional charge was for an additional battery.  I declined the additional battery.  Later, I went to my emails and couldn't find a receipt.  Later, I went through ALL my emails and saw an email from a seller with a name such as "DigitalSeller" or something like that.  It charged me $100 more than what I thought I was buying.  At first I thought it was a mistake since I made no purchase through DigitalSeller (or whatever its name was).  But apparently, PowerSellerDigital uses multiple names and addresses.  DO NOT USE THIS SELLER.  When I called for a $100 refund he became belligerent.  I will be pursuing this through the courts if necessary, because a person like this man should be shut down.
