Absent management no communication - Negligence

I generally use Europcar up to this point no issues. However, a recent trip I had two issues (1) dangerous vehicle due to brights not working (2) no invoice + no communication back after trying twice to get hold of someone.

I mentioned the lights issue to the guy receiving the vehicle in Durban. I then contacted the call centre after getting back to Cape Town. Was told by the operator the Durban branch will deal with my requests. I requested a call back from Durban branch. No call back came. Then messaged through the website online requesting support used the reference). No reply. Result was my card bounced the amount charged.
