Unfortunately....
Unfortunately, I bought the wrong level of education. There is no number to call which complicated things. I emailed and they got back to me in 2hrs. It took about 20 emails (all in rapid succession - so I was not left hanging). They were super nice, but I was getting a bit frustrated - if we spoke on the phone, I think everything would have been fixed faster. So I still gave them a 5 star rating because they were very nice and professional throughout.
