I am also looking to do this for the bridal store I bought my wedding dress from.
I paid her £707 in total but I canceled a cheque (final payment) of £507, when I went to the dressmakers and she told me that the dress wasn't the same as I had ordered. I was advised by the store owner that the dressmaker would fix it to make it look like the picture. She couldn't do it and advised me that it should have looked like the picture to begin with. I tried to contact my bridal store but I found out when I called that they had closed for 2 weeks, this was one week before I was due to leave for Disney and my wedding. I was devestated, all I knew was that I didn't have the wedding gown I had ordered and waited months for. I really wanted her to rectify the problem and I left messages and even contacted the Sales Manager in order to get this problem solved.
I ended up having to buy a new wedding gown, veli etc for my wedding as the dress I had, required way too much alterations and it wasn't what I ordered.
So now I am looking to recover £200 from her. I sent her a letter over 3 weeks ago, stating my position, but she still hasn't responded. So I too am looking into small claims.
Good Luck Natalie, hope it works out for you!
