I am trying to get a keyboard replacement for my Dell laptop. The technical support team has opened a case to this effect, but the service has been delayed for the past two weeks. I have not been provided with any clear reason for the delay, just vague excuses like the part is in backlog, the approval is pending, the shipping team is at fault, etc. Moreover, I have not been given any clear picture of when the service might actually happen -- every day I call in, I am promised a callback the following day with an update, which never comes. I am in this precarious situation despite having Premium Support Warranty. Can someone please suggest what I may do in this situation to get some help with having my laptop fixed?
