Learn to sew for customers

After waiting for more than the stipulated delivery time,I received a large size skirt though i ordered small. The skirt came with threads hanging, the threads were not even sewn in properly. the skirt didn't look like what I saw in the picture and worst of all didn't fit at all. I gave them a call to complain but the lady who answered gave me an attitude and didn't give me a resolution. she said the only thing they can do is to start the refund process which might take 2 months and with T&Cs. So I was not happy I ended up paying somebody else to alter the skirt so that was like 500 extra on top of the 700 that I paid. Appalling and disgusting. They don't know how to produce the products for customers, only for the owner as they alter on her.
