Unacceptable service and attitude

On Sat, 15 Aug, I took my daughter's S3 Mini in to the service centre (not even 9 months old, and already with multiple issues) and booked it in. I didn't have my daughter's pin code, so I called it in as soon as I got home. I was informed that the book-ins would be processed only from Mon, and that someone would call me on Mon or Tue with the Job Ref. No. Needless to say, no call. On Wed I tried to call all 4 numbers listed on the booking slip - all engaged. Sent an email to the service centre - never got any reply. On Thu Jeffrey called me with the Job Ref. No. - although he apologised, it certainly didn't feel sincere, and his tone became pretty arrogant when I expressed my displeasure at the poor service I was getting from Samsung. As is standard practice these days, his defense was \I'm only responsible for booking in the repairs""; it's now a further 3 days; and I've again heard nothing. This is the 2nd Samsung phone we've bought;and will be the last."""
