Refund for cancelled application

[moulie18]

Does anyone have a situation I recently had please?

I am i viting my mother as a visitor to the UK. I completed her application and found out that there is a typing error on her birthday (instead of 12th March, I put 2 March).

It says that once the application is completed, you cannot amend it, but cancel it, request a refund and fill another application.
I did the same, cancelled the application and requested a refund in 25th October.

My mother has TLS appointment in 14th November. But I have not heard from the HO yet.
Does anybody know how l9ng does it take to receive a refund?
I could not found their contact details to contact either.

Please share if you had the same situation.

Kind regards
Moulie.
