Shocking response to shoddy service

We have been loyal clients for over 30 years. 6 months ago my fridge stopped working. Mastercare sent out a technition who declared the compressor to be faulty. He replaced first time with the wrong one and had to order the correct one which we had to pay in for. It still did not work and he told me “ bad news” you need to buy a new fridge. I asked for a 2nd opinion and they sent a 2nd technition who said the problem was the PC board. He was unable to fix it and confirmed the bad news that I needed to buy a new one. The cost of replacing it with the equivalent side by side with ice maker was R20 000 I offered for Mastercare to come and fetch the new compressor that was installed unnecessarily but they did nothing so I sold the faulty fridge for spares. The person I sold it to got it working and it has worked ever since. I have tried to get Mastercare to acknowledge their error but 4 emails to the CEO , Westly falls on deaf ears. This is the most disappointing situation and very sad for pensioners who have always been loyal customers Mr Westly Rabie it’s about time you stood by your statement if valuing your customers
