Faulty product not willing to refund or replace.

I bought a Clarisonic Alpha Fit from Ubuy on the 28th of November, delivery took place on the 05th of December with I was happy with because its a Christmas gift for my husband. On the 24th midnight after unwrapping he put the Alpha fit onto the charging station for charging , after the 18 hours as instructed and the charging symbol on green we pressed the power button to start the clarisonic and nothing happened. I emailed Ubuy, they instructed that I upload a video with my problem witch I did. They them rep**** saying : 'Ruchier Nirvan (Ubuy)

Dear Letitia Van ZYl,

We are sorry to inform you that concerned department has denied your request as help window has closed for your order. As per policy, you can escalate issue for defective product within next 5 business days once you receive product. We are sorry but we cannot do anything regarding this concern.' How can the not do anything about this. I spend almost 3500.00 on a product that's faulty and they cannot do anything regarding this. So I bought a Christmas gift for my husband that's not working and washed +- 3500.00 down the drain. I mean this is like *****ing my money. When you buy a product and its not working its just right to replace it or refund it.
