According to the call I also received, it is Kelsy Seybold Clinic in Houston

Yes, it's Kelsey Seybold. They are calling to remind you of an upcoming doctor appointment that you had scheduled with them.

I don't use Kelsey-Seybold, and I'm getting calls with no messages

Maybe a phone system error

Just got a call from them and I do not use Kelsey-Seybold. No message.

Calls with no voicemail. Never did business with said company. Quite aggravating as this goes on.

Same, just got a call and I answered an one one was there, annoying indeed.

I received 2 calls form this number, last night and this morning, I called this number but no one could tell me who called.

Keep getting calls

Yep, I got it just now as well. I have screened calls. Instead of leaving their name for the screening, they left, “Hi, this i—“ and it cut off. THAT’S FOR YOUR NAME, stupid! So I sent it to voicemail and they hung up.
Hah... well, Ok then. I didn’t wanna talk to you either, I guess.

I receive 7 calls from  this number and don't use Kelsey sebold clinic sounds like fax Number and no one say anything very annoying.
