Stolen cell phone

I used Air-O-Parking from the 26th of December to the 30th of December. My son forgot his phone in the car, when we received the vehicle back the phone was stolen out of the car. I reported it on the day when we collected the car (30 December 2022), the driver who collected the vehicle said that he will report it and that they will come back to me. Nobody bothered to contact me with an update. I phone them on the morning of the 4th of January, the driver again said that he is 10 minutes away from the office and someone will get back to be as soon as he gets to the office, no way contact me. Later the afternoon of the 4th of Jan I phoned again and spoke to (I think the owner) who apologized and said that he will look into it. I heard nothing back until the 6th of Jan when I send him a WhatsApp. Once again, they decided to rather keep quite and did not reply. Tried sending them another message today (12 Jan 2022) will see if they bother to get back to me this time.
