National Truck Funding LLC Trucking company charges fees and send plates for half a year even though I paid for a year. Arizona

I got a truck from this conpany a little over 5 months ago and there are always fees that need to be paid... I always wondered why so many but now I understand. They call me 24/7 and they text my family memebers for payments. I told them multiple times not to call my family memebers but they still called 4-5 tines a day including texts. They told me to pay 3000 for a plate and they only sent me for a few months not even a year. Tey ask for additional fees and it is just so wierd how they talk to you and ask you for money.. they told us that sonce we got the truck that if anything were to break theyll pay half and i will pay half. Ones I paid half i got told that they dont cover it. I am so dissapointed and Idk what to do... i paid so much more money.
