My refund

I requested my policy to be canceled at the beginning of October affective from last day of the month, and I did this because my new policy was starting at the beginning of November, Discovery didn't cancel my policy, they just told me that my policy will be canceled, on the 27 of October they debited my account, the money i didn't even budget for, now I had two insurance companies debiting my account for the same thing, I queried this with them, they said they will cancel the policy and refund my money back, now it's a problem for them to refund my money back, I keep on running after them asking for my refund, they are not even giving me any feedback, this is annoying and irritating, they don't even deserve this one star, I just had to put it to be able to a write this review, because I am tired beginning for my money and they're behaving as if they're making me a favor with my money. I didn't even budget for this money they have debited, hence I requested for the cancelation at beginning of the month to avoid all this. I AM SO ANNOYED
