Hair system too dense? Incorrect colour

[Seanyy210]

Hi all I had my first system fitted at the start of July. However I am not too happy with it. The colour is too dark (medium brown) and it seems too dense and wig-like. I have since sent it back to get the colour lightened and the system repaired (it got all tangled).

I have posted a few pics of both the system and my hair before the system was installed. Please note my hair is dyed in the previous photos. (I'm naturally very dark mousy blonde).

I spent £400 on this system, so I would be very thankful for your advice and opinions.
