Fridge service in Malaysia

My freezer not cold any more so I ask the technician to come and check, they repair it and it cost MYR$280. There are the plugs which no longer function, last year I have the fridge repair and it cost me MYR$600. The motor spoiled and they change it, the motor of fridge cost MYR$500 today. The technicians are from USJ, Subang Jaya.

Above you are looking at the items that are spoiled from the fridge. I ask if there is any guarantee of the service, they told me No.
