Poor customer service

I called to cancel my warranty policy as my vehicle has been sold and settled and therefore are entitled to a pro-rata refund. I have sent the necessary docs in order to complete the cancellation. Its been about a week I have not received any communication regarding the status of the policy cancellation or my refund. When I call I keep being told that the cancellation process takes up to 30 days, which I think is *******. The policy must be cancelled the day immediately when I cancel, and I also deserve to know who is dealing with my policy and not being kept in the dark like I am now. I am very unhappy with the level of customer service at SAW.
