Charging two contracts at the the time

Good morning

I inquired about the two sims that I received with my upgrade. The one sim is working but the other sim does not. I have called in and written emails asking about my problem but haven't gotten any help.

I put the one sim in my phone and it works perfectly and then I put the second sim in my phone and it does not work at all. Please could I get some assistance with this?

This is extremely dishonest in my opinion to offer an upgrade but not to cancel the old contract. So I have been paying for two contracts of one which I do not even use nor was informed that I can continue using it or I can cancel it. In all the other cell phone companies when you upgrade the old contract is cancelled. Except for RAIN. I request that all the additional payments be refunded to me or you need to prove where I was informed that I need to cancel the old contract.
