Car spare key not received from Nov 2022

I bought a new Suzuki Swift in November 2022. The application and approval went thought sufficiently ,but the day I went to collect my new car ,I haven't received the spare key. They told me they will let me know when I can come to get it. I phoned and message Zenrico multiple times ,which did the contract application with me ,but unfortunately did not get response from him. I had to phone him and send messages. When I took in my car for services they said they will follow up on the spare key ,but still no response. I am a dedicated Suzuki user from 2011 ,but with this type of services I am forced to look at other manufacturers. I NEED MY SPARE KEY
