Our Dell laptop is under warranty. It has been keeping breaking down in the past one and a half years. In the last two mouths, our Dell machine has been unable to start up. Dell engineers have tried several times and failed to repair it. We have spent money to phone Dell technical support for many, many times. But they always find reasons or excuse to delay and postphone. Dell's technical support telephone line is always unclear. Furthermore, the line is sometimes cut off when you are talking and complaining to Dell staff. Poor quality of Dell products! Bad services of Dell!! Terrible technical support!!!
