Extremely tasteless service

The call center says I owe R67.00, the branch in Bloemfontein says I owe R372.36, but I paid R380.00 on Saturday. The manager at the branch comes with a ****** white attitude, plainly refusing to understand my complaint and simply says to me. \Give me proof of payment"and then he turns his back. I have been using the same method of payment for the past 12 months but this month it is clearly different. Can somebody pls explain this problem."""
