What should i do about our Dj?

So I have a long long post. I am having a destination wedding in Jamaica this year and our wedding planner is nice, but at first wasn't on top of things and was taking a long time to respond to my emails. Then we finally had a phone call with her where I told her that we expect a response that doesn't take 2- 3 weeks. We hired her for full service and she is recommending us vendors that she has worked with many times and according to her are "really great at what they do." Well the caterer is one of these vendors that she uses all the time. My fiance and I are foodies and eat mostly plant-based, so we told our planner this and asked who the company is that she is working with. Well she completely disregarded that part of my email that I had sent out. Then when I brought it up again, she said that the catering company doesn't have a website or Instagram. So we will be talking to this caterer through a phone call hopefully soon. Then last Monday my fiance and I had a FaceTime call scheduled with the DJ where we were going to finally meet him and discuss our music. We scheduled this phone call for 3:30 PM. And this was scheduled 2-3 days before. The DJ said something along the lines of "Sounds good. I will talk to you then." Well we try calling and he misses the call. Then he emails me an hour later saying, "Hey I just wanted to confirm when we are having the call." Umm. We confirmed 2-3 days ago!!! Then I said, "We just tried calling you, but we are free right now to chat if you are available." No response. I'm super frustrated at this point so I reach out to my wedding planner late last night explaining the whole conversation and how frustrated I am and that I am almost at the point where I would like to hire someone else or just rent our own speakers and have a friend or family member handle the music. WELL the DJ emailed me this morning saying, "hello I read your email. I didn't see that I had a missed call. I apologize for the miscommunication. Check your IG I sent you a message there so we can talk better." And so I go check my messages and he sent me a message that says, "Hey its DJ ___ i guess we can talk here. It's better." Then I just said "Hi sounds good." Then he says "Let me know which day you are available to discuss music for the wedding." And I said, "I'm free next Sunday, July 10th." Then he said, "Ok just message me here for a reminder. The meeting will be a brief one thanks."
Is it just me or are these major red flags? Why in the world should I need to remind a DJ of a meeting we have already confirmed?! I don't even know what to do at this point. We can't afford a very expensive DJ, but this more "affordable" option is not very reliable so far. We are having a chill laid back wedding with only up to 30 guests total attending. We are thinking of just renting speakers and using our own Spotify playlists and asking a family member or friend to handle the music, but I don't know what to do... I'm kind of fed up with wedding planning at this point.
