No service from Head Office

My MacBook pro was handed in at your Woodlands Branch for repairs last week. I was promised to get progress updates – no feedback received from your Woodlands Branch. Yesterday I phoned your customer care and the consultant was going to come back to me - no feedback received yet. Sent an email - no feedback yet. Filled in a "Contact Us" on your website this morning - no response. I phoned your Woodlands Branch just now and was informed that the call was logged at Head Office to collect the MacBook and take to Core Group - but head office has not done anything yet.

Can I urgently get feedback as to what you will do as my computer is under warranty.
