Cancelation request avoidance

Very disappointed in netstar, after sending multiple emails for over a week now to get my subscription cancelled, no one has assisted. First person to answer my email gave me the penalty fee, which I agreed to and asked that they proceed, since then that person never got back to me, I followed up with more emails, one called my phone for a second, before I could answer they hung up and sent an email to say they couldn't get hold of me to which I rep**** and reiterated that they should cancel with immediate effect since the car is W/O still not actioned
