Need help and some thoughts on my shopify store!

Hello Guys,

I used to run an independent brand that would operate on shopify. I used to do over 6 figures in yearly revenue/profit but due to school, travel and personal issues I quit focusing on it. Since then I've had lots of chargebacks, we're talking almost 60+, and honestly it was my fault for keeping the store up and accepting orders despite not shipping out on time or not even shipping out at all. I've refunded all the orders that were never shipped and shipped everything out but now I'm facing a dilemna. I want to continue selling on shopify and starting my business again, but I don't want to face the issue of having the chargebacks shut my payments, so I was wondering, would it be smart to close shop and start fresh (brand new page and account)? Please let me know your thoughts on this. Thank you guys.
