BAD SERVICE

I was sent a statement sometime last week and it showed me the amount payable which in understanding is what I need to get paid, not what I owe The lady booked an appointment for me to get a call on the 25th so that my banking details could be verified before payment. Today I call again and I'm being told that I actually owe Sars which I don't believe. Can someone assist me and give me a straight answer instead of being told this and that and customer service being ***********.
