I ordered a blazer of size l. Product is shorter in size and also there are many threads and stiches are open inside. The fabric is so cheap. They pushing me to keep the product with me as according to them they sent me size l. But there is no size tag anywhere or this is not about tag. This is about i wear all my another clothes with size l and that all suits me but club factory size is not standard. And the quality is main concern. Lots of stiches are open from different places. Also you can see the photograph attached. What kind of fabric they used and they teches me that there product is good. I have already provided them my product photos even then they are denying to return it. Please help me to return. Order num-so11507627.
