When my Samsung refrigerator broke down I googled and seeing a very good review I chose ADK Kooling Ltd for the diagnosis/repair and trusted they would be doing a good job. However, I was great my disappointed to have a misdiagnosis and also to be quoted a big amount for the wrong PCB boards to be changed. The engineer spent more than an hour to misdiagnose the fault. Initially he told me that 4 PCB boards might need changing which I was not very convinced with. So he carried on with his test and diagnosis and he eventually stated that the sub inverter board could be faulty but could also be the main PCB board as he has previously encountered a similar problem where both PCB boards had to be changed. I was given a quote of just over £200 for both parts to be replaced. So I decided to request Samsung to send an engineer to diagnose the fault. The Samsung engineer came a week later and spent no more than 20mins to diagnose the problem. He found the Assembly Module to be causing the fault which he replaced for £37.60 + VAT and labour at £95 the refrigerator was working perfectly again. The Samsung engineer did not find any fault with the Sub inverter board or main PCB board. ADK Kooling still charged me for the labour charge but at a reduced price of £65 (£95) after expressing my discontent with ADK Kooling service manager. I was really disappointed to have paid labour charge for an incompetent engineer sent by ADK Kooling. I was expecting them to raise their hands and accept that it’s been a mistake from them and wipe off the labour charge completely. Really disappointed and would never use this company again.
