Samsung Service Center — Poor quality service

I contacted Samsung Service Centre to register my request for the repair of my Samsung RT32 model refrigerator on August 3, 2015 Reference no. [protected]. The complaint was not attended before August 5, 2015 even though I have mentioned the URGENCY of my request as the device is used for the storage of INSULIN for a diabetic patient in my home. The engineer could not find the fault and just refilled the gas. The refrigerator didn't work properly even for 24 hours and again the complaint was registered on August 7, with reference no. [protected]. The engineer this time find the problem with 'sensor' and assured me that the same will be replaced with in 2-3 days. But even after 8 days nobody attended the complaint despite my repeated call at the service centre reminding them the urgency on medical grounds.
