Samsung worse service ever

I contacted Samsung on the 12th April 2018. for a warranty claim on my refrigerator compressor which is still a warranty. They said they send a repair company to fix it. The soonest they could come out was Monday the 14th. When the technician came to fix the refrigerator took off 1 ***** and by just looking at the circuit board said it is the board, Not testing nothing . He wasn't 2 minutes by my place telling me I must pay approxate R1000 for the board . I need a technician for 20 years and told him he cant just assume it that without test the board, and he reply was its the board I know its the compressor cause it does not get warm. The worse of it all thy haven't came back to repair it. Samsang called me and I told them and they told me they sort it out but no one get back to me. I receive 3 calls from Samsung service department telling me it will sorted out but have been disappointed on all 3 occasions . its the 23rd April and still waiting. All my appliance( 3 tvs, refrigerator microwave etc ) are samsung. The got the worse service . Will never buy a appliance from Samsung again
