I bought the ENTIRE series several years ago, I am a teacher. I went to use the online videos and they were gone! When I call, they say "ma'am they aren't gone we just are having technical issues." Well I gave them a week to figure out the technical issues, and they are still inaccessible. No emails, no follow-ups! So now, here I am in a digital world as a teacher (all the computers with DVDs have been taken from our building) without the resources that I spent hundreds of dollars on from this company. The customer service people are absolutely not helpful and just keep brushing me off. I am a very unhappy educator!
