A Rotten Apple .... MacAir

I was given a very special Christmas Gift in Dec'19 of a MacAir Workbook- it cost approx R23 000. I am a book keeper and wanted to finish the accounts on my Dell laptop before swapping over to Apple (which would then talk to my iPad and iPhone). The MacAir was opened during May and to my dismay was faulty from box ! It took 13 days for Apple to fix A COMPLETELY NEW UNIT with REPLACING BATTERY & TOUCH ID & MLB. I was given a Case No. to follow up with my complaint ********** 39579 from Apple support - a complete waste of time! I am a very disillusioned Apple customer !
