Elevatione Time Stops They forged my signature and then refused to return my payment when returning the product unopen Manila Manila

Elevatione had a kiosk and office at the Century Mall in Manilla,Philippines. On June 25 and 26 I visitied their store to check out their products. On June 26th I bought a tube of face cream for what i thought was $21 but I find out a week later when checking my credit card they charged me $2100. I had never been given a receipt and did not notice this until then. I was in a different city on vacation and flew back to Manila to return this product called 60 Seconds. They did not want to accept the return and could not give me a reason but took it from me anyway. I had the Mall Police with with me just in case as I did not feel safe. Now they refuse to rerun my money AND have their product to resell if they like. I made it clear to them I am a 70 year old retiree and could NEVER afford this product and how it was a mistake as it was over a month of my retiree income. Why would they not do the honorable thing. I had never used Philippine currency before my entire life, why would they penalize me like this
