Sos Appliance Repair

I recently have my LG fridge done(?) by SOS Appliance Repair Inc technician...before coming to my house,i stated in their website the problem of my fridge...their technician came (his name is Tom),he checked the fridge ,opened a small window with three screws at the back where the circuit board is located , checking his smartphone at the same time,i guess searching in the internet with the same problem as mine...he failed to fix it and he told me that i need a new circuit board and presently he doesn't have one the same as mine....he was looking for that defective part in the internet through his phone but he can't find it,he told me that the needed part is not available in the market anymore(i bought the fridge at Leon's just 3 years ago)....when the technician left i myself searched the internet for that part and was able to find it in 5 minutes and ordered one as soon as i found it (the part cost only $116)... i think the guy doesn't know what he's doing as a technician.The sad part was that he charged me $80 for the visit or consultation and $25 for the labor WITHOUT DOING ANYTHING AT ALL .I paid a total of $115 to a repair company that for me doesn't exist.
