Unpalatable T&Cs

Upon renting a van on the 31/01/25 i was disssapointed that the van quoted was not available. the second call from Avis was additional T&Cs, wanting me to bring a utility bill because my last rental was in 2021. do they ask for this item from all renting clients or is this practice discriminatory and profiling. i raised my objection with the manager and requested that they amend their T&Cs. she promised to call me back on the 10th and seem to have forgotten about me.
