Hello,
I think you have been overcharged for that work because it's more than twice (than) what I had to pay.
Is "than" missing here or can the phrase do very well without it?
Thanks.

Hi,

You don't need 'than' twice. Either 'twice as much as' or 'more than twice.'

Hi,

If I use 'twice as much as' instead of 'more than twice', should 'what' be not used ?

In other words, the sentence becomes : I think you have been overcharged for that work because it's twice as much as I had to pay.

Thanks.

Your sentence is correct, Stephen. You are right that you should not use 'what'.
