Disgusting Service from Samsung

Our fridge had a few issues, but it was in operational working order. Samsung sent their fly by night technicians to 'fix' (Onalds Electrical.) They came a few times because they could not fix it. They changed various parts which was paid for. When they left the last time., the fridge was completely broken and not in working order. We asked Samsung for a complete refund including the call out fee and to restore the fridge as how they found it or replace the fridge. They only refunded for the parts that we paid Onalds. How can an International Company give such poor service and subcontract their repair work to people who do such shoddy work. Beware of buying Samsung appliances. Their after sales service is nothing short of disgusting.
