Can we NOT opt to neither Select Open nor Select Basic?

Early this year, we were asked to chose between Select Open and Select Basic Licensing.  A few weeks ago, we had been billed on some over usage on some software.  For our better control on the usage, we prefer NOT to opt neither of the above licensing scheme but to keep our OLD Select Licensing.  Where it is impossible for any over usage and no Quarterly Bill.

Pls advise and confirm, can we revert back to OLD Select Licensing?
