Shopify complaint: Holding my money for their personal gain of the interest my money will make them

My account has been open for a month and they decided to wait until I got a nice payment from a customer to hold my money for 4 months they said. They had a while month to review my account and they choose to wait until 12 hours after the order was paid for and fulfilled. Leaving a customer with free items. I can’t afford to wait 4 mo this for my payment. What they are doing is holding my money and 1000s of other people’s money in their personal account so they can make money off of the interest. I’ll be filing a complaint with every single place I can so that everyone can know what they are doing. They said they can’t give me the reason for what they are doing. That’s because there is no reason other than personal gain for them off of my money. PayPal Venmo and several others have been doing this for years and no one seems to care. Well I’ll b damned if they are going to illegally take and hold my money. No where in their policy does it state that this a practice they use. They can’t just up and make rules up as they go. And people can’t always afford to go after them. But we can sure ruin their name so no one makes the same mistake I do by trusting this company with my money. I want my money now. I’m not waiting 4 mo this for anything to be returned to me. It’s my money and I want it now.
