FromNeq !'s Review Sourced from Google
**I am not a client*** I saw an ad on Instagram (which I reported) for an online assist job and they are scammers. If anyone wants you to apply on WhatsApp it’s automatically a scam. Also the way the company is replying is suspicious (“In no way do you have control over your marketing strategy 😂😂)
