Service (and Jeffrey in particular): 5 stars. Billing: 1 star. You sent us an invoice that said: Amount Due: $250, Amount Paid: $0. I emailed you to say I was mailing payment. The next day I received an emailed "receipt" showing "authorization" for you to charge our Visa on file. (We had given no such authorization.) I emailed again to say "Hey, like I told you, the check is already in the mail - so don't cash it." You responded to say "Okay, we won't cash it." Spoiler alert: you cashed it. Now you owe us $250 and this is really unprofessional. I emailed your customer service a few minutes ago to ask how you plan on refunding the extra $250.
