Billing for two insurances at the same time.

I hate this provider now. I have been a loyal customer since 2000. They just lazy to return my call or respond to messages. I have two insurances with mtn, it's Epic 3 and Callsure. They both debit my account monthly. When ever you call mtn you stay in-line for 30min, nobody picks up the phone. What irritates even more is that when you make changes you don't talk to your clients. You changed my insurance and u never communicated. I also called Callsure they say you never cancelled with them as well. So stupid mtn, I want my money debited since lady year August. This is the third and the last communication I am having.
