Poor after sales service

I bought a Ford Ranger in August 2020. With purchasing the vehicle, I gave my consent to include a unlimited warranty in the deal valid for 2 years. The purchase contract & all other documents were signed electronically meaning I could only see & read the documents, only AFTER signing. This includes the warranty policy schedule (which was never sent to me via email). Now the warranty has expired. I was never informed or aware that I must pay for this expired warranty for the rest of the finance period meaning I have to pay for the next 4 years for something that does not exist. Now typically it is my problem as I have signed for the "terms & conditions" as claimed by this dealership but not informed by them of ALL the information 2 years ago. That's what I call unprofessional & ********* business. I will never do business with them again, ever.
