I recently purchased a secondhand vehicle privately from an employee of a local business. The car was advertised for sale outside the business in their car park and when I paid for it, the transaction occurred inside the business premises. The car was not advertised with any faults and was told that it had a new motor. I do not drive much, so a few days later, when I took it for a long drive (5km), it overheated and fortunately was about 1/2 km from my regular mechanic. I took the car to him, he had a quick look but as he is busy and has a 3 week waiting list, I booked it in for a inspection. I managed to get home. I did not dive the car until my mechanic was able to have a good look. Upon inspection, he informed me that it needed a new head and would cost in excess of $3000 and that the seller was aware of this and failed to declare this. I rang the seller's place of employment and I was informed he was away on holidays and had to wait 2 weeks before he returned. On his return, I rang him, explained the situation, especially on how I needed the car to attend my doctor's appointments and as a result of not having a car, I missed 3 appointments and had to delay an operation as I could not afford to pay my doctor. In short, he told me where to go and threatened me telling me "to come down and see him and he will sort me out". Let's say he just waved a red flag in front of a bull. I then informed him that I would take the following course of action. 1. I would make posts all over social media telling my story and advising followers not to use the business as they employed an unscrupulous person and to ring the business and either a) waste the business' time by asking salespersons questions about their products with no intent of making a purchase or b) demanding they refund on my behalf. It is not illegal to post my story online, I will not encourage others to threaten or abuse both the business and its employees including the person who sold me the car. I cannot help it if some nutter wished to take it further. I will not encourage or condone it. I am just telling my story. I was threatened by the business that they would sue me if I slandered them over the internet. My response being it is only slander if it is not the truth and what part is not the truth? The car was advertised on the property of their business. I went inside their business and paid an employee of their business. I have every right to name their business. Bring it on, I say. So far, I haven't made a post as yet. 2. I would ring every 5 - 20 minutes demanding a refund, or ask stupid questions, tell them I rang the wrong number and hang up or simply ask, "how is your day going?" Basically, the logic being if I am going to lose my money, I will ensure you lose it 10 fold via other means. The aim being the business loses money due to my time wasting with them either pressuring their employee to either refund my money or them to sack him for being a liar for me to stop. I commenced this phase last Friday and continued today. I now have been threatened that if it continued that they will go to police tomorrow and have me charged. I ask what can I be charged for under Criminal Law? I have not abused, threatened, blackmailed or extorted anything. Thanks in advance for your assistance.
