I have a Basic account but am a business owner. I would like a LindeX™ Tier Review (as suggested by the customer support gal on the phone) to up my limit on how much L I can buy & sell. How do I do this? I need to sell enough L to equal $501.06 (the closest I could get to 500) to pay a bill asap. I can't wait several weeks or months at the basic 2,500L limit. I'm not a new player, I'm 490 days old atm. Help please?
