SmartMouth I've been using Smart Mouth mouthwash for like 10 months now, but recently it messed me up real bad

I've been using Smart Mouth mouthwash for like 10 months now, but recently it messed me up real bad. The quality of their mouthwash gave me some serious side effects, man. I had to quit using it and switch to another brand. I reached out to their customer service and told them all the deets about what happened. I even asked for a refund of $80 'cause that's how much I spent on their mouthwash. But guess what? Smart Mouth didn't even bother to respond to my complaint or refund request. Can you believe that? I mean, come on, I bought so many bottles of their mouthwash, so I deserve that $80 back, you know?
