Nightmare with Nightgaurd

Nightgaurd canceled my contract but still debited my account for 2 months, when I asked why the contract was canceled, no one could answer. No management is avialable to discuss with and they never respond to any emails. I had a telephone call from someone is the financial department informing me that the contract was scheduled for cancelation on the 20th December but could not tell me who requested the cancelation, but according to the Nightgaurd control room it was canceled at the end of October. When asking for a refund the request is totally ignored, now they want me to fill out a cancelation form explaining the reason for the canelation. I am short 2 months premiums for services I did not recieve
