Removal of Rental vehicle ate one of my garage slots

Saffr0n: We have reviewed your ticket and have discovered an error in the messaging you received and have provided you the correct information. When you sell back a rental vehicle, the garage slot does not disappear because it is unique to your account as there are no options to remove (i.e. sell) it.   Do you have a screenshot of your garage after 9.30.2015 as this was the last time you earned the E 25 and an additional garage slot? You have not purchased/earned any since then so it will show the correct number of garage slots you have.
