Pathetic Service from Samsung

I called the customer service center more than a week ago to log a fault for my samsung 58" tv. I was told a technician would contact me within 48-72 hours. To date nobody has made contact with me. I called the call center to follow up and was made numerous promises that they would make contact with the assigned technician and call me back to let me know what was happening. I still have no feedback and neither has anyone bothered to contacted me to update me. Truly pathetic service from a so called world class company.
