No feedback after 4 weeks

I handed in a faulty tablet at the Smart Care centre on the 17th of Jan. I was promised that I would get feedback and a quote within the next 2 days. 2 weeks went by after which I called again. I spoke to another agent (can't remember his name) who informed me that a quote would be sent to me shortly. Another 2 weeks went by. Last week I spoke to Raheema and after I explained the situation to her she promised that I would be contacted within 2 hours but yet another 4 days have gone by with no feedback.<br> <br> What do I need to do to get a faulty item fixed? Do you not measure turnaround times on repairs? How can this be acceptable to a company that claims \the world's best products deserves the world's best service"?<br> <br> """
