Non existent service and customer support for iStore

Absolutely dismal support with malfunction which was identified shortly after purchase. The failure to address and solve the issue during warranty resulted in the MacBook been now out of warranty and having to pay over R 11,000 for a new screen. Apple US directed me to iStore and iStore simply refers that unit out of warranty despite having records showing that issues since purchase indicating manufacturing fault. No reply from the core group and unable to reach any customer services or manager at the group to raise the issue. Wouod not recommend or buy an apple product id the most important component , customer service is missing despite being a premium priced device.
