Bogus Bonus Cars

I have bought a second hand car from Bonus Cars in Guagga Road, Pretoria with its problems of plugs not working at the above dealer and made payment through my FNB business account acc. and it reflected that the money went through. The problem started when they repeatedly forced me to loggin for the 4th time to send the proof of payment. Salesman was Mac called his brother to fiddle into my account and I refused because I have emailed them and downloaded statement 4 times on their computer. I decided to reverse my money because they started insulting me in front of my husband. I drove to the nearest Guagga Mall at the FNB branch . I took the papers of thee car with me to show as a proof that I have paid for it. I was followed after a while waiting on the queue and Mac grabbed the papers and bank documents ran off with them to the parking. I ran after him asking to give back but Mac and his gang about 5 people strangled me pulling me side by side to get the papers I took back from them. I am traumatised by the situation hence I have opened a case of assault at the nearby police station.
