Continuous Billing

I honestly do not know what is happening at this company! I cancelled my policy with this company BEFORE the inception date and still got billed for a tracking device what was already installed BEFORE thinking of dotsure! I was refunded for the first month and the agent confirmed with Netstar that I had a active policy with them before. The second month comes along and I get billed AGAIN for the tracking device! The policy was CANCELLED before the inception date and I continue to pay Netstar with the contract I had with them BEFORE dotsure. FFS this is the worst company I have ever dealt with!
