Emporio Armani Sweatpants Unravel at Seams Three Weeks After Purchase from Brandy's

I purchased a pair of Emporio Armani sweatpants from Brandy's online store for approximately $114. About three weeks after receiving them, the seams started unraveling. Deteriorating this quickly is unacceptable, especially for a product at this price point.

I haven't contacted Brandy's yet because I don't know how to reach customer support or what steps to take. I do not want to cancel the order—I simply want an exchange for an undamaged pair. My order number is B442AL5315N.

I request that these unraveling sweatpants be inspected, that an exchange be processed as quickly as possible, and that I be provided with a clear, detailed update.
