L'Core Paris review: Service was overwhelming. High pressured.

Last November 5th in LasVegas at the Westgate Hotel, I was pressured into getting a 10 minute demo in L'Core Paris which turned into at least 45 mins. The two young girls who spoke broken English are very good at working on your insecurities. I am 82 yrs old and don't use makeup. Once they had my credit card, that was all they needed to "talk me into" other products and before I knew it they had charged $6000 on my card! I felt so pressured, I just wanted to get out of there. The worst part is that when the box arrived at home I couldn't open it. Last week I finally did and there was no invoice! I had called one of the girls early on and wanted to return the goods but of course she wasn't going to help me. On line you could; it a store you had to go back. I have hospital bills to pay. I want to return the products even for less than the full amount. I have been unable to sleep. This has upset me so. I paid my bill and probably shouldn't have. I am embarrassed and very upset.
