NESTAR - Tracking Company

I will never recommend Netstar again to anyone. First off, all I've been with them since 2021 on the highest plan but never received the service I paid for. Every time I quired this with them they always have a different excuse (This is a Toyota box). The Toyota box has nothing to do with my Netstar tracking device. Once I was fed-up and requested the service that I paid for or a refund they installed a new devise in my vehicle. Not even a few days has passed, and this device wasn't working the way it should I've logged so may calls along with phone calls and nothing happened. Once my husband got hold of one of the agents, they agree to cancel my contract with immediate effect, and no one needs to pay no one. I have been debited ever since and every time I dispute the payment; they keep on sending emails and handed me over. If I want to cancel, I have to pay a ridicules fee which was agreed to not to pay and no refunded needed. I'm absolutely furious for them and want my refund for 3years of service paid which I never received. This is mainly about the panic and tracking that wasn't responding to their systems.
