Useless service- Faulty products

I Wish I can give them no stars at all. My wife ordered me a Christmas present in November from them, it was a mavic air 2 battery charger for the car and a battery for the same drone, received it. I only opened it in January and both the charger and battery did not work. I contacted them to replace or repair. They collected it very quickly and since then it is a struggle to get hold of anyone. No one can provide me with feedback. So basically they stole our money from us.
