Legit or ****????

The absolute worst! We’re being sent letters of demand for a sars debt that we don’t even have. Our emails and calls go unanswered! The letter says we owe sars a lot of money -(which is totally damaging to a small business)- for VAT, but we don’t. We are up to date with SARS. We aren’t being rep**** to. We hold for hours on the phone and emails aren’t being responded to! Is this company legit or ****?
