How do I get version 27.4.1 back??

[miriam32455611p9ne]

I'm a student and to have there be NO customer service on the weekends to get help is maddening.  I've lost an entire day trying to get my version back.  Drop down menu doesn't say OTHER VERSIONS.  I"m so freaking frustrated that Adobe thinks 24/7 means Monday thru Friday for the business community.  For the amount of money we pay this company it'd be nice to have customer service open on the weekends WHEN STUDENTS STUDY.  How do I get version 27.4.1 back and why did it change to version 28?

Is this the dropdown you're referring to?

27.4.1 should be visible under the option Carlos shows above:

Also if you don't want versions to change without your input in future, turn off auto update:
