Hair nightmare

Elizabeth
I just had my hair coloured and cut and it has turned out to be horrid. 
I'm naturally a very dark brown colour and the hairdresser did foils which have ended up giving me a horrid mousey brown/ blonde colour with snippets of my natural colour. 
Since I have a reddish tinge to my skin it looks absolutely horrid and I'm devistated.  
​Guess this will be the first and last time I do anything to my hair other than a cut! 
​I've sent a message to the hairdresser hoping she can or will fix the colour :(
​Has anybody else gone for a colour and it has turned out looking terrible?
