Business ProfileforColor Street, LLC

Hello there, I am hoping you can help me with an ongoing issue I've been having w/one of your local Jersey companies. I've been purchasing products from Color Street, a company located in ****** ********** for over 5 years as I am a Stylist who buys and sells their products. Since March 2023, they started overcharging me on sales tax on nearly every order (we are talking like 60+ orders) and at times, the overage can be 100% or MORE in sales tax than is required. None of my orders are local purchase, ALL of my orders ship to ************* where we have 7.85% sales tax and agree that is the amount they should charge on the destination sales tax as I am registered locally to pay those resale taxes. The issue, despite bringing the overcharges to their attention multiple times (30 + times) over the past 15 months, Color Street continues to over charge me in destination sales tax and ALSO adds NJ sales tax on shipping fees that are sent to me via USPO or FEDX. This doesn't seem right to be double dipping on taxes and continualy over charging me on destination sales tax as well? Is that normal for NJ businesses to do this? They will refund the overcharge on destination sales tax ONLY IF I bring to ther attention after 1 or 2 emails, but have done nothing to resolve the ongoing overcharge issue and wonder what if any recourse do I, or other customers being overcharged in getting this resolved without me having to call them out every single time. I have asked their customer service agents to put me in touch w/a supervisor or someone that can resolve this.....but for more than a year the excuse is always "we are working on this issue" but nothing ever happens to resolve this. Thank you in advance for your advise and assistance if you are able to help. Sincerely, ***************** ************ ***************
