I had a car accident on the 25th of July 2025 and Affinity said I shouldn’t take any tow truck besides the one that they recommended and I did as advised. While awaiting the claim process which was declined, the problem now is that the drivers door control system was vandalised and my battery went missing in the process. I’ve been trying to find out who took my battery and what happened to my door since 16 September 2025, all they say is “we are still investigating.” I’m done fixing my car I need the battery and no one seems to care.
