FLR(M) - Wrong IHS Number on Premium Booking Service App

[vAvAv00m]

Applicant: Myself (Australian, on shore in the UK)
Partner: British citizen
Visa: FLR(M) family route partner visa - first application
Date of submission (premium appointment): 28th Sept 2018
Current applicant visa: Tier 5 mobility
Date of current visa expiration: 20th October 2018
Application status:
Documents gathered and form filled in
Premium Service appointment booked on 28th of September 2018
Manually applied and paid for new IHS number

Problem is in our in person Premium Service application via this link: https://visas-immigration.service.gov.u ... nt-booking, I have entered my Tier 5 Mobility IHS number, which is incorrect, instead of leaving it blank.

Out of worry, I then afterwards manually applied for a new IHS number via the online application form which I won't be submitting since I can only choose to submit in person or online.

I called the Premium Service helpline twice, first lady Jade said that as long I have paid for a new IHS number, and corrected the IHS number on the printed application form, I should be fine but when I called again and we have Anne on the phone saying that it is a disaster and we need to cancel our whole application and also appointment, re-fill in everything again and re-book our premium appointment, paying the whole 1600 pounds again and apply for a refund.

The discrepancy in advice is maddening and it is very difficult to secure a Premium Service appointment, that's why we aren't sure how to proceed here.

Could someone urgently advise on this? Any help will be greatly appreciated. Thank you.

Just write the IHS number on the printed application
