Poor service

I have a 2022 nissan qashqai but the main problem with the car is the keys and battery!!! I have already purchased 3 keys which do not work. The first time I was told it's either I have dropped the keys and hence needed to buy and pay for the programming, which i did. 3 months later, the very same keys are giving me the same problem. I went to nissan to report and i was told to go to the dealer that replaced the keys. I informed nissan on their webpage and no one responded. The car is still within warranty but has been having a battery issue. I again informed Nissan and it seems i need to go to a battery centre to diagnose the problem and possibly get a new battery. I am trying to establish if the battery issue is a common problem with nissan and how many times will i have to change the battery? The after service at nissan is very poor. I have been using Nissan Centurion but replaced the keys at Nissan Woodmead
