Poor service

Barnards TV & Appliance Services (Pretoria). Do not make use of this company. We have a problem with our Defy Freezer. It keeps giving an error on the screen. The first technician came at a call out fee of R650. And immediately said it is the PC board. He promised it will never happen again once the PC board is replaced. Replaced it for R1500. Three days later the error came on again. The second technician said it is the defrosting element. But the third technician said ot is not faulty. The second technician starting taking out some ice that was inside the freezer by force and broke the gas pipe. After some time he returned to fix the pipe and regas. And it is hot, so many of the frozen foods started defrosting. After they left, the error code is still on the screen and hopefully the freezer will freeze. But now we might as well buy a new one, since they messed it up already.
