Box Office Top-up

On April 26th, I went onto my online profile and topped up my Box Office account with R350. The money went off my account, and the screen indicated that the transaction had been successful. I didn't check my balance until about a month and a half later when I wanted to rent a movie and I've sent communication to Box Office twice through their website, and I have not received any feedback. My account balance still has not been updated. What is going on?
