I was not clearly made aware in advance my booking was with Autounion. Missed initial collection at airport, pick up driver did not use our names. We were directed to wrong car and car we got had several dents and marks, not great condition externally. On drop off large Q of people and no one from Autounion speaking to tell us what was happening. Hard to park car due to busyness (cars everywhere) Once I approached a staff member they just took the keys and said that was car returned. No check on car made and no confirmation given on deposit refund. When I asked our return driver to airport they didn't no the refund procedure. Office tucked away round back of block all in all just didn't feel very professional.
