I submitted the application for uk visa for me and my son. After that registered on vfsglobal.co.uk, added both our reference number, uploaded a couple documents, and clicked continue button, which took me to select the shipping options. I want to upload more documents, but its not showing the documents upload option any more. I am not able to find any help or contact number for VFSglobal. Any help on how to upload documents to my application would be really appreciated. Thank you.
