Business ProfileforMercedes-Benz Mbrace

I traded my 2018 Mercedez Benz for a new 2023 Model on Oct 2022. I called the ******************** and told them that I no longer owned the 2018 model, but I want to continue the stolen vehicle tracking service to continue to my new vehicle. The person that I spoke to said they would process that. I was never told that there are two different service for older vehicle and newer vehicle. I was never told that I had to cancel the service. They continue to charge me the subscription fee of $199. On October 2023 I found out that my subscription was expiring at the end of the month. I called ******************** and told them that I paid $199 and it should'nt expire. They proceeded to tell me that the $199 was for my older model vehicle and was never cancelled. I told them about the conversation I had back in October. I told them that since I no longer owned the 2018 vehicle I was provided the wrong information that I should get a full refund. They said they can only give me a partial refund. They provided me a partial refund of $68.15. I am asking Mercedez Benz to give me the rest of the refund of $130.85 because I should'nt be paying for service that I am not receiving specially if I was given the wrong information.
