UKVI contact email address for Tier 2 dependent Visa extension UPDATE

Hi,
Could anyone share the email address for the Tier 2 Visa (dependent) extension office in London ? I have been waiting 6 weeks now, there is no news. Bit worried. Submitted Biometric 6 weeks back. This is where I sent the documents.:
Tier 2, Tier 5 Standard
PO Box 74576
LONDON
SW1P 9WP

Many thanks,
GP

The standard time is 8 weeks. There is no way you check the status of the application.

Suggest wait till at least 8 weeks has passed.

Hello

Did you receive your visa ?

I have been waited for 4 months ((
