Shocking service

I am a huge fan of Samsung products however when they do go faulty it is near impossible to get support. The support is disgraceful. I recently logged a call for a fridge as it constantly switches to holiday mode thereby turning off the fridge. After numerous calls and numerous no shows a technician did come out however the Service Order sheet has a different customer name, different address, different appointment date, incorrect defect description with a comment stating that the fridge is Unrepairable. Internal wires for the display are damaged. Shocking quality control. My other concern is that I’m assuming that Samsung has a lifespan on parts which should be communicated to customers as I have no understanding as to why the entire unit (computer board) of the fridge could not be replaced. Now the difficult decision, should I invest in another Samsung fridge or go for another brand.
