Worst Customer Experience Ever!!!!

I bought a samsung monitor on the online store and wow was I in for a suprise how shocking the service was. I had found a dead pixel upon receiving the monitor, I phoned and was told to take in to their repair centre which I went there and was told to go through the call centre as it is an Out of Box failure. I then called them back and was told a technician will collect it, still nothing has been collected in over a week! Don`t bother buying anything on the online store nothing will get sorted.
