Seems it is OK for Spark to email you an invoice but, too bad if you want to reply with a query. So I am supposed to know that the above address is “No-reply”? Fail on two counts of customer service. Sadly I am not surprised, just annoyed I have to go find the username/password and login. What a pain!
Another useful lesson with a real life example for students in how not to build intuitive and customer focused systems and processes.
