Nissan of Huntington

I brought my 2016 nissan sentra in nissan of huntington beach service department because the check engine light is on. service advisor says evap system needs service. I paid 943.00 dollars for the service but ater 2 days check engine light is on again! after 2 days service advisor says charcoal canister needs service and I ask him him what if after a few days the light will turn on again and he says I just have to pay again! So I paid another 934. 00 dollars for the service. after 2 days the check engine light is on again! I was very mad with the service advisor or the mechanic whos working on my car! I shared my experienced with my neighbor and he opened the hood of my car and check my engine and notice that a hose is disconnected going to the evap? this employees at this dealership are bad people! if anyone reads this review, dont take your car to this place, this place is very bad!. I have the receipts to prove my story!
