Svelte gets you to sign up and gets you to invest another 1200 dollars never changing the guarantee they do not adhere to it. My wife has been trying to get a refund. No luck. They didn't follow through or answer emails daily like they said. Breech of there own promises.
I'm sorry to hear about your frustrating experience with Svelte.
It sounds incredibly frustrating when a company doesn't honor their guarantees or respond to concerns promptly. Have you tried reaching out through other channels like phone calls or social media?
