Mercedes benz lenasia broke my car

I had taken my car in for wheel balancing and alignment on the 20th of January 2026 i was helped with kindness from staff on this day i left the car in the morning at around 07:18 and left to go to school and yes i was quite happy with service but on return i paid waited for my vehicle around 16:13 when i started my car the first light i seen was check coolent level which i had checked in the morning which was perfect and then i said never mind my house is not far I'll just fill antifreeze at home when i arrived home and when i had opened my bonnet i found my water bottle covered in thick dark black oil and when i opened my bottle cap oil started spurting on to me from the water bottle and when I phoned Mercedes benz in the morning they listened to my story said come in when i arrived the manager of services Mr Singh was absolutely rude to me started screaming at me then he pulled out a picture of my vehicle's engine and on the bottle was messed with polish which he told me no my car had a water leak which i know is impossible since i know my car and drive it daily he then got to an agreement and said okay i should bring the car to him at Mercedes i then asked him how do in bring in the car if all the engines oil is in the cars water bottle he tells me okay no you know what I'll send a flat bed but you must pay for the transportation as well as for his team to check how this had happened later on in the day I went back and i asked him was my car test driven he says yes it was test driven the team does a 4 kilometer test run which I then proceeded to ask him were you with your staff members when the car was test driven he accepted and said no he was not so to my thinking he probably knows that my car was driven absolutely insane for this to happen i don't have the funds to pay for this incident i mean my car came in perfectly fine only had to do balancing and on arrival it says check coolent level and when i get home it magically has oil on the water bottle as well as all the engines oil being in the water bottle and he says to me' him and his team is not liable for any damages due to them not touching anything on the engine and they only touched the suspension i am highly disappointed and currently sitting with out a vehicle how do i get to school and work and I mean my car is a daily runner so how can this only happen the day on which I send the car to Mercedes benz and also I've never touched any parts in the engine only serviced the car

Highly disappointed and very angry Please do assist me with this matter......!
