Stage 2 partner surcharge

Hi Guys,

Thanks for answering all my questions.
I applied for GTV stage2 for me and my partner. MY IHS got generated by making payment but my dependant surcharge got generated without any payment( though visa fees applied)
Any thing got changed recently or they will charge at later date??

Please assist since both of us planning to travel together. Any delay i can expect??

ah i got it from another post. date of expiry is a bug and i messed up there. I had to cancel visa application and start a fresh copy.
This time it charged me more than 3 years and i need to ask for refund from home office.
Please let me know the refund process.
