Incorrectly charged a radio fee now I’m getting the run around

I was incorrectly debited a radio fee for the month of December when this is not supposed to be charged to me because of the type of alarm system I have.

When I called in to query this I was told a credit controller would be assigned and initiate the refund. The last communication is received from this credit controller was last week Tuesday. I’ve sent her 3 emails with zero response. I’ve tried calling everyday since and can never get through.

I just want to be refunded the amount that was incorrectly debited. Why is that so much of a hassle.
