Complaint regarding unresolved issues

On the 30th of July 2025, I bought a pre-owned Kobi (Mercedes-Benz Vito 116CDI). After eight days, the vehicle developed a diesel gauge problem that was not functioning. The vehicle was returned on the 12 of August 2025, but it was not attended to. On the 19th of September, I went to fetch the vehicle, only to find that it had never been attended to. In addition, both wheel caps on the left side were removed, one of the headrests was missing, and there was a scratch on the left door.

The manager and the salesperson were alerted, but the issues have still not been fixed to date. I have tried to contact Hyundai Hatfield as well their head office with no luck.
