be very careful of netstar

we took out a contract with netstar a few years back. in august 2018 we sold the car that was covered by netstar. we sent an email to customer services at netstar to tell them we no longer needed their service. there was no response. we finally heard about netstar cancellations and sent them an email telling them we no longer needed their services. we then get an email from netstar to say sorry, we signed a three year contract. we dispute that. we were not told at the time that we signed a three year contract. had we been told, we would never have signed such an agreement. the car was more than 10 years old at the time. we have asked netstar for proof of the contract and proof that we were told of the three years. in the meantime netstar wants an exhorbitant fee to settle the contract. this is simply unbecoming.
