long story. logic board has been replaced 3 times, other parts replaced too. i'm working with a guy over the phone, he told me to get my laptop repaired one last time, and if it acts up again, he would work for a replacement for me. gave me his extention and such. i called him 2 days ago, left a voice mail. no call back yet, and no call back until monday now i guess, since his voice mail says 1-2 business days. though it has been. so my two questions are: should i wait for him to call me back? (i tried calling him back a few times, only got the voice mail) or should i just talk to another apple rep? i mean, does it matter who is "handling my case"? also, if a replacement is issued, are they (or will they) issue me store credit for the amount of the replacement machine instead of giving the machine itself? reason being, i'd like to upgrade it and pay the difference but i won't be able to until next paycheck.
