I would suggest visiting a Samsung Experience Store or Samsung Service Centre for support.
They'll be able to help or escalate this for you.
That said in the UK when an item is purchased it's the seller that has to help under the Sales of Goods Act 2015. Consumer-rights-act.
" Your rights under the Consumer Rights Act are against the retailer – the company that sold you the product – not the manufacturer, so you must take any claim to the retailer. "
You'd need to check your own countries support acts.
