So, some news on my side... Although I don't understand what it all means...
E-mailed to UKVI 13 December to ask about status through their paid service and didn't get a response.
Called UKVI following non-receipt of response on 2d January, they said that they couldn't see my GWF number in their system. the operator said they'll escalate my case, but I didn't receive any written confirmation either
E-mailed UKVI again on 12th of January following non-receipt of any confirmation... received a response: "Thank you for the information you have provided. We escalated your case to the relevant department on 03/01/2018. You should be contacted regarding your case within 15 working days from the date of escalation.
Please allow the 15 working days to pass before contacting UK Visas & Immigration International Contact Centre again should you not receive any further correspondence."
Today received an email from Sheffield (VISAINFO.SHEFO@fco.gov.uk) "Thank you for your enquiry. Apologies for this delay - I have passed this on to the relevant team to be looked at. If you have any further enquiries, please visit our website at
www.GOV.UK. Kind Regards"
So... no idea what it all means...
