Program flawed, no quality assurance

For years (and previous versions) are the same mistakes in it: update on the program menu System Freeze completely, only hard reset helps. An additional non-functional PDF printer is installed without being asked, remembering Product Registration is not permanent suppressible, an unnecessary "information service service" is installed without permission and eats resources, although it uses the program as the average user more than 1x per year. Data transfer from the previous year not is still not working.
The calculated tax refund amount is, at least in my fiscally very simple case, in any version (2014, 2013, 2012) have been wrong. Bottom line, you get the tax office only half of what the program displays, although the built-in function "tax inspector" will not make mistakes.

After creating the tax return, the program starts a satisfaction survey. When "Do you have the telephone support availed" with "No" answers the question, you will be asked how satisfied you are with the telephone support. You must answer every question before you can click Next.

By whom this software is developed? Quality assured by whom?

Just out of curiosity I clicked through me by the survey:
"Which operating system running on my smartphone?" "In what social networks I am active?" "Age group?" "What is my income?" "Single married?"
They want to know even more than the tax office Yes! What do they do with this information?
And "if I was interested in a customer-oriented beta test?"
So the question would be answered, such as the quality of this software is.

Thank you, never again. The last 3 editions I have long hoped that the teething problems will eventually be eradicated, but unfortunately that's not the case. It is time to grapple with alternatives, such as the free, offered by the tax office ELSTER software.
