Money taken from center console during MOT

Hi, I (21M) took my car to get an MOT at a very well trusted company in England. I have a MOT and service plan I pay 37 a month for. I emptied most of the car at home but as i was running a bit behind I decided to just get there. At the MOT centre I left my key in one of the self service stands that lock your key away. I then left at 9:30 and got a call at 12:30 that my vehicle was ready to be picked up. Once I'd retrieved my key and went into my car. I'd realised I had left some money in the center console. I am 99% sure I had £180 in there and I know that the mechanic had been that compartment as the locking wheel nut had been left where the money was and not on the seat where I had originally left it as instructed. What can I do from here? I've notified the company and they said their service manager will give me a call on Monday (Saturday today). Is there anything I need to be aware of or do? The money isn't mine and is my dad's who I was picking up on his behalf due to him being in palliative care.
