Hello Ingo,
Hope this email finds you well.
I am writing to you because I got the feedback that you have concerns on the case response time. First, I have to say sorry for the bad experience you have received from Microsoft.
Then please allow me to make things more clear. As far as I know, your case has not been responded to for a long time because the American team currently has 2,000 cases waiting in the queue. And as far as I knew, engineers in this team have been long time being overloaded and currently can only have BW focusing on A cases, which resulted in your cases not being responded in time. We have already notified the American team of your current situation via email and upgraded your case to level A in the backend, hoping that the American team can prioritize your case.
On the other hand, I have already feedbacked your concerns internally and believe we could see the improvement in the short future. I think you could receive the timely response next time if Microsoft could have another chance to work with you, but I am still not sure this could 100% happen. However, if you do meet the same problem next time, I suggest you could write email with case ID to below addresses. If the case is Windows related, we will be then notified and pay attention to it.
csprcsupport@microsoft.com
winbcwsdm@microsoft.com
Additionally, if you no longer wish to continue with support, you can leave us a message, and we will take responsibility for issuing a refund. We deeply apologize for the unpleasant experience.
If you still have anything unclear, kindly reach out to me.
Thank you for choosing Microsoft.
Best Regards
Rosy
