Sorry about your bad experience, that is not good feeling .I have had similar experience with the drone did not responding after a mission with Pix4dCapture ,none command responded to make safe landing resulting a crash
Parrot support just made all impossible to assume responsibility after all evidences of malfunction they just ignored my problem
Last fly also without log recorded ,almost two months fighting to get a real support without trustful answer
I started a legal action against them buy also till now are ignoring the lawyer with not responding to the case
very annoying checking further what to do to stop this mishandle to customer
