Useless Service/repairs Centre for Istore

I would like to point out for others considering purchasing Apple products (I doubt I will get a reply). I sent 1 of my Mac books into the store and thus send away to be looked at. It didn't want to boot up or switch on. After less than a day I get sent a quote that I need a new screen and main board and this is R22 000. I tell them to send back to me. I took my problem to Youtube and I found a solution; I opened up the back of the machine a fiddled with the key board and viola, my Mac was all better. I sent a disappointed email to the service centre to advise that I as a layman could fix my Mac and they couldn't- strange. I had no reply and chased up with 3 further emails to finally receive a reply saying its not their responsibility as I had my mac returned. This week I had to send in my older Mac book as it wouldn't charge. It was sent to the service centre and I heard nothing. I get a mail saying the unit is on the way back to the shop. I email to say thanks but \what was wrong with it\". This was 4 days ago and I have had no reply. Tomorrow I will collect my mac and see what surprise awaits me. Apple only want money and their after-sales and service is below bad service."
