When I applied for dependent visa, it didnt asked for the payment. I got the IHS number without making any payment. I tried different ways to get to the payment page, but I didn't get through.
As I got the IHS, I went ahead. He attended the biometrics with VFS global on 19th September.
On 6th Oct, I got the link for IHS payment of 181819.12 INR from
no-reply@www.immigration-health-surcharge.service.gov.uk
But that link didn't worked. It was saying that top up key has been cancelled.
The email stated that make the payment of 181819.12 (INR) by 13 October 2022.
If the payment isn’t made by 13 October 2022 your visa application may be rejected or refused, and you’ll have to apply again.
I contacted UK visa support the next day, but they are giving very automated replies and asking me to just wait. I also mailed
ihs.sheffield@fco.gov.uk, but haven't heard from them
