Disappointing service

So I decided to cancel my insurance with them simply because of the benefits I have found a better offer .So now when I cancel the lady who assisted me said she will send me a cancellation letter three days after I called again because they debited the whole amount now the second lady who tried to assist said she will tell the First Lady who assisted me to call me on Monday it was Tuesday when I realized they are never going to call me because they must refund me.I didn’t appreciate their service at just because I’m terminating our partnership they don’t care about my queries they don’t want thus to end our relationship on a good note.I’m very disappointed.
