50/50 chance of getting what you have paid for

I ordered my wedding dress and 7 flower girl dresses, first 3 came and were perfect- exact match to image and correct size. Next 4 came however they loosely resemble the first ones, silver and light blue sequins rather than silver and navy, embroidery is black rather than navy, no beading to be found and embroidery is a rushed and simplistic design -different to the first ones.
My wedding dress was perfect and 3 flowergirl dresses were amazing shame other 4 don't match and now have to go buy 7 new ones- after spending almost £450 on the perfect design on this site.
My order has proved it's 50 / 50 chance of getting what you have paid for.
Currently being ignored by their after sales team after being told that they cannot see anything wrong or different between the 2 sets of dresses.
Since looking closer at their website the pics of their sales team have turned out to be photos they clearly found on image search ( found 2 of them to actually be semi-famous people and one comes up on many sites labeled picture of pretty blonde when I have reverse image searched them).
Suppose my fault for not properly looking into company before ordering from them, unfortunately I only started looking into them after I had placed 3 orders and put all hope on fact that I order things from China quite often over Ebay and have never had any problems.
