Next business day repair adverti***** is a lie

I phoned Dell on Wednesday the 4th of march 2015.<br> The reported my problem and said the next day (5th of march 2015) a technician will come and fix my laptop. After a struggle the technician told me the parts dell provided him with was faulty. He promised me the next day (6th March 2015) he will come with new parts. Next day no one arrived i phoned dell back and they gave me the excuse the technician was at my premises and phoned yet i received no phone call.<br> After a fight with them i told them i need my laptop fixed urgently so they sent some one back that same day.<br> AGAIN IT WAS TOLD TO ME THE PARTS IS FAULTY THAT DELL PROVIDED, Unfortunately by that time the call center was closed.<br> I phoned on Monday morning again and they have no answer for me except they escalated it and i need to wait for feedback<br> Never in my life have i had this bad service from Dell, it does seem to me their service is going backwards<br> They simply do not care that i am losing money due to a broken system as long as they keep making money
