Business ProfileforLarson Porsche Of Tacoma

My wife and I bought a used Porsche Macan S at Porsche of Tacoma on November 7, 2021 for $76311.44. At the time we bought the pre-paid service package for the car, which was supposed to cover the cost of all our maintenance for the next few years. The cost of the care package was $8520.00 before tax.When we tried to use that package for routine maintenance we performed at Porsche Tacoma on December 21, 2021, the service manager informed us that the service plan was not active, and furthermore a service plan could not be purchased when buying a used car at all. He also mentioned that we should get a refund for the service plan and someone will be in touch shortly. When nobody got in touch and no refund was issued, we contacted the dealership again on April 1, 2022, asking for the refund. The financing manager at the dealership (*************************) responded by e-mail confirming that the service contract was not valid and that a refund would be issued to us, but again no refund was issued. We contacted the dealership by e-mail again on June 28 and on July 8, 2022. This time nobody at the dealership responded. I would like Porsche of Tacoma to refund the money we paid for the invalid service contract.
