Frustrated and disappointed by Netstar

I am honestly getting frustrated with Netstar, from the month of October they started deducting money from my account, I have a product with Netstar but through my insurance, they are not supposed to deduct money separately and this has been the case until October, I called them and made them aware of this and I was told the debit order will be cancelled, then immediately after that call I received an email from Netstar with a new contract which I never app**** for, when I called them back they said it was a system error and that they will cancel it, I am still getting debited by Netstar and I have no idea what for, this month they debited my account twice and I keep disputing and stopping them, but the debit orders won't stop. I am so disappointed with this company
