Isolator Fitness

I signed up for a promo last year. After receiving my promo, I purchased some product one time. The product wasnt bad but for the price it was a little expensive. After the first purchase i started to receive text about discount. I opted out on the first time but every month after i have received a text from them. I continued to opt out. In December of 2017, I threaten their support with an FTC complaint if it didn't stop. For 2 month it had stopped until this February where i received another text. I have filed an FTC complaint now hoping that it will stop now. This company is very sketchy in terms of receiving their text messages and I am worried about what they are doing with my information.
