I've sent an email to help@tes:
I feel I need to comment on the absence of any form of communication from yourselves regarding the issues ClassCharts has been having this last 30 hours. I appreciate, especially working in IT myself, that sometimes things don't work correctly, nothing can have an 100% uptime. The bigger problem here is the complete lack of acknowledgment or communication out to your customers that there was an issue and that it was being worked on. After the data breach issues last year that you all swept under the carpet as a non breach - one can only assume similar again without being assured otherwise. You need to do better.
