Disgusting Service!

I bought a LG fridge/freezer 2.5 years ago from Hirsch's Homestore i have always bought all my appliances from them. On Sunday night, we had a power surge and the next day my fridge/freezer had totally defrosted and was not working at all. I called Hirsch's Homestore and logged a call with them, paid R790 and they came to assess my appliance. I got a report to tell me my compressor was faulty from wear and tear???? (My last LG fridge lasted me 20 years with not a days trouble, which my friend is still using) They then told me my compressor has a 10 year warrantee and will be replaced by LG. LG contacted me and told me i have to pay R2500 but they suggest i get the LG technician out for R700 to do the assessment to check nothing else was wrong with my fridge? I called the manager of Springfield Branch, he told me they had done there job and if LG needs me to pay again, so be it! Not at all helpful and rude! Why did Hirsch's Homestore not tell me to contact LG directly in the first place? Why must i pay to have the same assessment done!
