Help my burgundy hightlights have turned our purple!?

I have my hair coloured in very defined stripes of blonde and red. For a change I just got burgundy ones put in instead of red and they have turned out purple and horrible! Any suggestions please as to what has happened and what I should do. Can anyone tell me if I can have the purple highlights turned to ones in a dark blonde colour. Don't care what I spend as long as it can be sorted out. Any comments would be so much appreciated. Thank you for your help.
