Lavish Skin Care Dermabright the product burned my face, they will not return my $90. which they quoted $4.95, I m on disability Santa Ana nationwide

I ordered an anti-wrinkle cream from a Dr Oz site and it was called 'Rejuvenate' but somehow I received lavish and dermabright. I cancelled Lavish in less than 14 days but Dermabright's number was difficult to find and I did call but they said it was too late by 2 days. A normal company goes by business days. They charged me $90. for some cream that burned my face. They were rude and went on the review site to see they have scammed alot of people. I am 60 yrs old and live on a disability check. I thought I was getting a $3.95 cream. It is not even the one I ordered and they refuse to give me my money; can you help?
