Delay in tier 2 general priority visa (5 years)

[mkhamis]

I applied for the tier 2 (General) priority visa. My CoS is for 5 years. I submitted my documents and had biometrics collected on 30.07.

On 20.08 I called the UKVI and the lady was surprised that a decision has already been made long ago but no one got in touch with me. She said since 15 working days have passed then she recommends that we escalate my application. I did so and until today (29.08) I did not receive any updates from the UKVI (except an email early August saying that they received my application).

I'm an Egyptian living in Germany. This makes it super inconvenient since they've got my passport.

I called the UKVI multiple times, but they say they cannot do anything until 15 working days have passed since the time I escalated. I'm starting to wonder if the escalation could have delayed things further and why in the world was it recommended if that was the case.

Is there anything that can be done besides waiting?
