Cotosen review: Online clothing retailer; do not do business with this company

I ordered a XL sweatshirt from an online company called Cotosen, which promised a quality product. I received a small sweatshirt made with inferior quality material. I emailed them 4 times over 4 weeks asking for return/refund information using the customer service link on their website and received no acknowledgment. On my 5th email to them, I said I would go to the Better Business Bureau if I did not hear from them. The company gave me the following return address:

Liu Rongfeng
Address: Gate 2, Zhongtang Warehouse, Sanhe Logistics Park, Chajiao Avenue, Zhongtang Town
City: Dongguan
State: Guangdong
Country: China
Zip Code: 523000
Phone number: [protected]

The package was sent to me from an address in Hawthorne, California. When dealing with returns online with reputable companies, I am usually provided with return shipping labels and an expedient return process. I did not receive anything from Cotosen other than the return address information. Needless to say I was not comfortable returning the item to China with the hope of getting a refund.

I am writing this complaint to warn other consumers of this company's shoddy online sales practices and to stick with large established and reputable retail businesses.
