GOOD FEET Fast Paced Sales Scam for over $770.19 OM AHA Nebraska

Went to this store here in Omaha on11/19/15 for free foot test. Sales girl after test ran to baqck room and said I needed  to buy a $139.00 pair of shoes plus tax of course. I said not.She then returned fromm abckroom with two sets of small plasrtic inserts they stock I guess for all.She said this is what In needed and gave mw to set of pads for the covers of the arch support..I was never told or quoted any prices. just wrote up and not have my glass case I did sign. When later I looked the bill of of which was all numbers it was a total of $770.19 for two small sets or arch supports and all sia no rerturns or refunds !-The sales girl was a fast talker and told ne little or ever gave me a total amount due .--This was a total scam  of and older person for sure. I have filed a BBB report and also blocked the charge.. A shame  this company is not honest or explain the charges. I also do not think the sales girl had did not much kniowledge of a persons foot problesm as problem is still present and do think I was fir wrong but cannot go back as know will be charged more. My advise is to have all explained or go other shops for foot problems.
