BADLY NEED YOUR HELP. Appointment coming Xray not cleared

[StaffNurse0608]

Hi! I am a nurse here in the UK and I'm processing my husband's visa for him to come here with me. We booked a visa appointment application to submit the documents on the 21st of July. However, his TB certificate wasn't cleared yet and he has to wait 2 months before he can have another x-ray after his sputum test. It wasn't tuberculosis at all per the doctor, just some unclear xray result. I just want to know if it is safe to:
A. File for a refund. Will my IHS and VISA application be refunded despite being 3-4 days away from appointment? How many percent will they deduct from my payment?
B. Reschedule the appointment till October and hopefully, he'll be cleared by that time?

*Also, I recently moved to another address like 2 days ago as we had problems with the landlord and the address we've submitted was the previous one*

PLEASE I NEED YOUR ADVICE. Thank you very much!

you need to check from the country u applied, but as i understand, if u dont submit your application/docs, your fee is returned.
