DHgate Newstarstore I bought a wig and it had a bald spot and DHgate refused to do anything about the seller who ignored my messages. Internet

 I ordered a wig from DHgate and when I received it, it had a bald spot at the back. I immediately went to the site and wrote a message to the seller. The seller asked that I provide pictures of the wig and I did, then the seller promised to send me a new wig and a week and a half later I had not heard anything more from the seller. I decided to write again and I was asked to go through the same process again, which I did, and that was when I was offered a discount on the second order. I refused to place another order while I had paid for a wig I can't use and lost money at that. After that, the seller ignored my messages. I wrote DHgate and they said I should communicate with the seller and reach an agreement. After two weeks of on and off messages DHgate told me to open an after sales dispute. Each time I tried, it didn't work. I wrote back and each time was told to open a dispute. Between communicating with the seller and DHgate a few weeks passed then they wrote to say I should have opened a dispute within seven days of receiving the wig, and that nothing can be done for me at this point.
