Incorrect information provided to the customer

Refund on payment and incorrect information given to the customer. I bought a part at Hyundai the Glen, only to discover it was incorrect called the dealership informed them of the matter and was advised to return it for a refund. The part was returned on the 7th February 2026, when I called the store today to enquire as to when should I expect my refund. I was informed that Head Office is responsible for realizing payments, the branch is not sure when refund will be paid and I was promised a call back after the branch has enquired as to when I will get my refund, I took the liberty to call Head Office to find out the process, to my surprise the information provided to me was incorrect everything is done at dealership level nothing goes to Head Office regarding refunds. How could a customer be misinformed regarding processes and I am paying for storage were the car is and the mechanic is getting impatient with me as I need those funds to proceed with fixing my car.
