Visa Renewal via Dropbox - No updates


I submitted my documents on 24th May 2022 for renewal of my US visitor visa which expired on 22nd May. 2022 I have been checking the cgifederal website which states Document Delivery Information:

On the website, my application status is ‘Application Received’ which was last updated on 26th May 2022. VFS global has no contact numbers though the exec who collected my documnets mentioned I should receive a response in 10 days (max 21 days). Could someone please help me understand why this is taking so long and if there’s anything I can do get an update at least?
