Can you remember what was agreed during your consultation? Did you ask for balayage? Generally, clients opt for some balayage lighter pieces leaving their natural colour as the background. That way, when the hair grows, there's no obvious line of demarcation.
Your natural hair colour looks much lighter than the hair in the picture and to achieve that look, it would have needed colouring much darker between the highlighted pieces. Then you would be left with an obvious line of regrowth within a few weeks between the dark brown colour and your lighter brown hair. It would also be an expensive look to maintain as you would need it re-doing every 4-6 weeks.
