Newsflash: Frustrated with agent

TL/DR: agent doesn’t communicate with us, advocate for us, we are under contract and don’t know what to do….My family’s home is currently under contract. Our realtor has gone on extended travel 3 times this past month(once since we went under contract). They have not warned us of this and have not had a POC for the absence and communication has been very sparse to non-existent. Since going under contract last week, the communication, lack thereof, from our realtor has been rather frustrating. We have not received any email from the transaction coordinator for what the process looks like. We have asked for details on inspection timelines, what to expect, etc, and have only received vague texts, and messages as if we are stupid and the emails have been sent(they haven’t). We’ve tried to call, we’ve asked them to call, but on Instagram, we can see they are having a fabulous vacation. Through forwarded texts from our agent during this time, the buyers have asked us to leave several furnishings behind for free, we of course said no and gave them the option to buy them instead. They persisted on some other items for us to just leave. We told our realtor these requests were making us uncomfortable and concerned saying no to leaving our stuff for free might impact the sale of the home. We provided a list of items we are willing to sell, and if the buyers want furnishings, refer to the list, everything else goes. We asked our realtor to take over if anything else is requested to say no. She hasn’t and on 2 occasions, texted us saying buyers requested such and such items. This has my wife and I paranoid the buyers will pull out of the contract. Our realtor has further texted us saying, “it’s normal to leave items (expensive) behind for free” uh, WHAT??? Aren’t agents supposed to advocate for their clients? And if it’s normal in this state, why was that not addressed when going over inclusions and exclusions prior to listing? We do not feel like our agent is advocating on our behalf at all. We were super impressed during our pitch meeting and had high hopes. Sorry if this feels scrambled. We are scrambled and anxious. We have never had to deal with an agent with this lack of communication. What do we do? How do we tread lightly to not piss our agent off, but feel reassured through this process?I will humbly shut up if I’m being too dramatic about this. Thanks and sorry for the long post.
