"I am sorry to hear this, it does appear that it was courier damaged it on its way to you. I can look into sourcing the damaged parts for you, if this request is approved and if the parts can be sourced, would you be able to fit the replacement parts yourself? If not, would you prefer to return the tank to us?"

I'm not really sure what to do. I've never build any models, or replaced or added things to any rc vehicles, so not sure if I can fix it myself.
If I return it to them, and they fix it, it could be damaged once again during transport, then I'd be back to square one. The ideal solution would be, they let me keep this tank, and send me a new one that doesn't get damaged on it's way
No matter what I choose, I'm still stuck with a tank I cannot use, at least for a while.
