Very disappointed in the results

I got one syringe of kysse two weeks ago and am very disappointed in the results. I paid $1,200 for my lips to look exactly the same (minus some very large bumps on the inside of my mouth). I’m going for a follow up this week and will be discussing with my provider to see if I can get at the very minimum, a partial refund. I’m so upset about wasting that much money to look exactly the same, and I see many posts of people saying the same thing about kysse. This was my first time getting lip fillers so I don’t have any other experiences to compare it to, but I do know my lips look exactly the same.
