TaxJar Sales Tax Automation

The customer support on this app is ATROCIOUS. We were locked out of our account for OVER a week. Their customer support is in India and each response is 24 hours or more. It's fine as long as it is working. The customer support is one thing but one month when we imported older orders into Shopify it counted ALL the orders even though the dates were over a year old. We had AUTO file set and it deducted $85K from our bank account and it took a few days to get it back. I am SO DONE.
