I have a Latitude 5530 I received new in Nov 2022. in November 2024 it would not apply windows security updates to windows 11 pro.I purchased ProSupport with the laptop and so I called Dell Tech Support. Last week, I decided to get this problem resolved and called Dell Tech Support - After a number of hours over a few days, the Tech told me it was a windows problem and that I should call microsoft. I did and spend several hours with them trying to fix the machine. It did not fix it. They sent me back to Dell. More hours beginning on Tuesday and by the time we go to Friday, the machine was useless - nothing the Tech told me to do made any difference. They said a Tech would be on site the next business day which would be monday. Sure enough I got an email to tell me the name and phone number of the person to expect and they wluld be here between 1 and 6 PM on Monday. I phoned the tech at 4 PM and he said he was tied up on a job and was going on vacation, so someone else would be out the next day. No One came out. Called again on Tuesday. I was told they ordered the part and it was on the way...then I got a notice that the part was delayed, Fed X was now at fault. I asked to elevate this and the Tech said he did - the I called on Wednesday and that tech told me is was elevated but it hasn't been 24 hours so no one looked at the "elevated" status. It left me wondering what the "elevated status" was for. I told this guy that there was supposed to be next business day service to have a tech here. He explained that happens only when everything goes well and sometimes it takes 2 or three days. I asked for the FedX Tracking number and he said he would send it to me - he did not. By the way, they shipped this part to arrive by "end of business day" instead of for delivery by 10:30 AM. This work order to have a tech on site was written on Friday, it is now end of wednesday. Thursday morning I called again - tech said he would send the tracking number - he did not. The part is still missing but their status report shows a serial number for the part which only appears once the part ships. I was promised that this was again "elevated" and a supervisor would call me by 6:00 PM. It is now 8PM - no call and no update on the status of this on site service, a service which is supposed to be "Next Business Day". Tomorrow is Friday. I have no confidence that the part has made it to the person who is supposed to make the service call. I have no call from any supervisor and I have no appointment notice for the repair. So bottom line is that pro support does not live up to the sales pitch so save your money. Tomorrow is the 5th business day since the order was entered and no one at Dell seems to give a damn. I will never again buy Dell and when these systems are replaced they will be replaced by another manufacturer. What a shame.
