This company promised to make my "idea come to life"- this did not happen and they NEVER told me that I would have to spend thousands of more dollars to actually have the app created. They lied and now I'm out over 3k. They even promised to give me a refund back in October and I have never heard from them since! Now their phone doesn't work and no one is emailing me back. I will be filing a lawsuit soon if I do not get my refund and will be filing a complaint with the FL attorney general.
