I applied for my wife for the dtv spouse

I have my dtv since last year. Now I got an email that the request got canceled because:

Your visa application has been cancelled. You have entered your name incorrectly.

The name is correct written same like on the passport also with middle name. I try to contact the embassy in Frankfurt Germany via phone and email since a week. No response

Any ideas ?

DTV obtained, Los Angeles consulate. Rejected first try. Received email after 4 grueling weeks that I had not typed my name exactly the same or had added or removed a space in typing my name, so different compared to my passport. Lost the $400, nonrefundable - that hurt! No response from Thai Evisa folks about details for my rejection. LA consulate responded by email just saying the money is nonrefundable and I would have to do a new application. Applied again, though I didn't know the exact mistake I made. Carefully typed my name...

Received based on Workation. I have a LLC, incorporated a few years already, and work is now done online. I sent incorporation paperwork, local city business license paperwork, and an affidavit (Googled examples of this after reading notes on this forum) attesting I am the owner, sole worker, all work done online, will have no Thai clients, etc. Sent current account statements. Driver license for proof of residency. Copy of passport. Current photo.

Everything same as first application. Paid again. Approved this time in approx 10 days.
