No to Netstar!!

Hi there, I signed up with Netstar, February 2020. Netstar was fast in signing me up, no problems.. Thru the lock down and hard times I never skipped one payment.. In January 2021 after 11 months with Netstar, i sold my vechile, the same day i phoned x 2 to let Netstar know, to deactivate the old vechile, TAKE NOTE!! I never asked to cancle my subscription with Netstar, only to deactivate old car and put trekker in New car, after phoning Netstar twice i got an answer i will be charged a fee.. That was perfect for me i will pay the fee... End of January debit went off for previous car, no longer on my name or my possession, after numerous calls, emails, I even went to Netstar Facebook, asking for changing of vechiles, till today nothing has changed, I do have all the proof about phoning, emails trying to sort this out.. NO RESPONSE OR A MSG WITH REF number, yet February 2021 debit went off for the old car, last night i got an email of my traveling log.. This is privacy for the new owner yet i have all the details. Netstar is very unprofessional in responding to matters, now i want to cancle but cant even do that. The people who is working there seemed to be confused in the work the do as every call is a diffrent, call agent and its diffrent story.. This is people i have to trust with my life and car.. UNEXCEPTIONAL, TO NETSTAR I MIGHT BE A NUMBER BUT FOR ME, ITS MY LIFE.
