What should I do if my DTV visa status is stuck after approval and I have a flight soon?

Hi first of all thank you guys so much for all the guidance, advice and help...this group is amazing.

Now to my confusing situation.

I applied for a dependent DTV Visa in Frankfurt, Germany early October, on the 6th of October they asked for more documents which I sent, then on the 14.10 I received the good news that my visa is approved!!! It was amazing and we bought our flight tickets the same day.

3 days later my status all the sudden changed from approved to request interview. Then I received an email on the 16.10 for an interview on the 20.10 at 10 am.

I went there yesterday, they were very friendly and kind, i greeted them in Thai, they laughed and were impressed with my pronunciation xD they asked me a lot of questions and I was quite nervous....

I brought up the situation with the approved visa and they told me, it's a glitch and if they grant me a visa, I will get a new one.

My status has not changed since the 16.10, also not after my interview, which is a bit concerning for me :(

Our flight is in 8 days.

My husband DTV Gott approved in less than a week.

Am I being paranoid? Should I reapply for a DTV or at least a tourist visa so I can fly to Bangkok on the 29....?

Our flights are non refundable, we also have a dog :( I'm so frustrated, worried and confused :(
