Horrible service from customer service agent

I created a gift registry online, and when a guest purchased online from it she let me know the registry did not update the item as purchased. I sent in a query, and the agent first let me know it will not update when the gift is purchased from the gift registry online. He then sent a further email to say it will only update when purchased online. We then had a back and forth where I explain it did not update, and he tells me it did. When I sent an e-mail with a screen shot showing the registry had not been updated and the gift had been ordered and already delivered to my guest (I registered for a throw and the guest received a baby blanket, by the way, the item was only described as a throw on your website but it seems anything is possible with your company) he just informed me the guest did it wrong. Do you not believe in taking customers seriously and at least checking out queries sent to you? He now informed me if we get double gifts we should exchange in store, which is the extent of his assistance on this issue. You just ignore my query and assume I am at fault, which is highly unprofessional.
