ShipStation Orders & Inventory

I was over charged $249.00 for 3 labels less then 3oz each. tried to contact customer service I was on hold for over 2 hours. after that all they did pushed me to stamps.com also 3 hours on hold. and all the parent company stamps.com did is gave me an email address to postal service to file a claim. I have been with those companies for many years very bad customer service no one to talk to.
