Angry isn’t the word!! We paid £1464 (or so) twice so assumed there was no underspend, she did say both applications were less than she thought but never said how much.
I hope you got that £1,300 or so back from her... you gave her £2,928 and she applied for one visa worth £1,464 and one worth £89... thereby fleecing you out of £1,375.
The total cost for both visas plus IHS surcharge should have been:
(£1,464 + £600) x 2 = £4,128
But your lawyer would have paid just
£1,464 + £600 + £89 = £2,153
Once piece of advice for future applicants:
ALWAYS fill out and pay for your own application. DO NOT let a lawyer do it for you!
Personally, I would want to double-check and research it all myself (probably the scientist in me)... so I wouldn't trust anyone else to do it for me

We are now applying for our daughters. I know you’ve stated before but is the choice of ‘dependant child of a settled person’ correct to choose? Just checking our online application now to make sure it’s correct - do we now also need to pay the £500 surcharge?
Yes, that's the correct type.
It's £600 surcharge for this visa. You should have to pay it but there has been a glitch in the IHS system whereby it says child dependants don't have to pay it, and it won't let you do it.
So you will probably have to send off the application without paying and then wait for UKVI to contact you and ask you to pay it (usually right before the decision is made).
