You will get plenty of that at your office sales meetings, office training, CE training, board and association training.

.* No calls accepted to review receipts: I have asked Jenny several times for the last 3+ weeks to get on a call to review the receipts and all of the items that are in the house, I have given her several deadlines to resolve the issue, she has never accepted any of my invitations to join any calls despite me pleading her to do so as my credit card payment is now due and has a 29.99% interest rate if not paid.I have found several people that were also affected with just 2 facebook posts.
