Netstar

I have been a Netstar client since 2017 and in 2022 I sold my car in July and I informed Netstar through a call that I am cancelling the contract. In September I realised they still deducting and I called i again I was told to drop an cancellation email which I did. With that done they kept on deducting up until I blocked the debit. They still trying to milk payments for the contract I cancelled in September
