Cancel, don't even try take my money on my bank

I regret the day i signed up with this Netstar, my advice to the public don't you ever give your details or take any tracking device with this company. I cancelled their feetment without even them to come fit on my car, now I called them and texted them that I'm no longer in need with thier services that's not even 24hrs.but now the lady by the name of Candice who was assisting she's throwing words on me because they want to slide this cancellation so that it looks like I'm still on their contract and deduct my money. I advice look for a different car tracking companies than this one just stay away they not helpful at all
