Delay in getting skilled worker Dependent visa

Hi All,

I made an application for extension of Skilled Worked Dependent Partner on 01/04/2024 along with primary applicant and dependent child. I made the visa application online by submitting the required details and completing the bio-metric verification via the UK Immigration ID check Android App from my phone.

The primary applicant received skilled worker extension on 06/04/2024 and Dependent child received visa on 27/04/2024. But I have not yet received my visa.

I received an email from Home Office on 08/04/2024, mentioning the below:
“We are unable to conclude the application currently as we are awaiting a decision to be made on your sponsors application.”

But as mentioned my sponsor – Primary applicant, received BRP before 08/04/2024.

I made a complaint on 12/06/2024. There have been no communication from Home office. Is there any way to escalate it further as I need to travel outside of country soon.

Thanks
