3 weeks and counting.....really???

I took my phone to Samsung on the 05/09/2015 for the LEd to be replaced. I was told that they will notify me via sms of the progress. I did not receive anything by Wednesday after making numerous calls. On Thursday 10/09/15 afternoon when I called again I received an email quotation. A guy Jeff I think told me they received stock and I will most probably get my phone same day. After awhile he called to say they still awaiting parts. I have made numerous calls, haven't heard anything from Samsumg. Does it really take 3 weeks to replace an LED and front camera.....the service is pathetic and as a result I am not considering a Samsung phone in future.
