Purchased a sink from the online store. Before I had even received the order it went on sale. I called customer service to request a refund of the difference. They said they don't do that. I asked for a store credit. They said no. They said I could return the sink then order a new one. I asked if I could return it in store, they said no. I asked to speak with a manager, they said no. Not helpful or customer oriented. The sink seems cool at least.
Rejuvenation, here is my order # WO00297162 if you want to fix your crappy policy!!!
