ScanDigital review: Charged me over $885!!!!

I am going to have to get a lawyer! Scan Digital has made my life a living HELL for the past five days! I had a Groupon coupon, (like I have read on SEVERAL other people's complaints about them), and they said they would use it, and then wanted to charge me over $150 then I said no. If you can't do the work for the Groupon coupon don't do it! Then Scan Digital says that Groupon coupon WILL cover it! NOW, they have put over $885.00 on my credit card! Several calls to Scan Digital, my Credit Card Company, and I put a complaint in with the Better Business Bureau, I am going to get this charge taken off! They had NO AUTHORIZATION to do this this "company" is a FRAUD, SCAM, and I will make it my lifetime goal to spread the word!
