1. My PC did not boot up2. The Engineer who attended did a mistake and I lost my data due to his mistake3. I am expecting a huge compensation from Dell. But still Dell Senior team has not responded.4. They said battery has gone. They charged me extra money for visit where I had premium support.5. Yet to hear on refund.6. Since 20 days, Dell Engineers are coming and doing half work and are escaping.7. No Seriousness at all. None has rectified.8. I have been sitting in front of PC calling them from 9.00 am till 6.00 pm everyday.9. They just call for a second when my line is busy and suddenly drop an email stating that I was not reachable. Really Pathetic.10. Engineers are happily working from HOME, Actually WORK FOR HOME.11. I do not know in what way and what words to use on them.
PC no boot, lost data
