FAILURE TO REFUND INCORRECTLY DEDUCTED MONEY

I bought a phone at this branch and used my visa card , they deducted the payment twice. on the day of the purchase the teller told me the amount would reverse automatically after 24 hours, this was not the case. I therefore went back to them the following day to inform them the money was still outstanding and since then I have been passed on from one person to the other within the department and have not had any of my money refunded. I am now at a point of reporting this to the police if I do not get any immediate action from this brance.
