Allumiderm Scam

I was scammed by Allumiderm and ad was on Facebook. I was told to pay shipping and handling $4.95 for trial size and later was charged 89.95 and when I contacted company I was told they wouldn't refund my money. Normally a trial size is 30 days I was told I didn't contact them in 14 days. The company is using Ayesha Curry (Stephen Curry wife name) . The women I spoke with tried to get me to purchase more by offering me a discount of 35% and when I said no she said well what about 50%.
