Hallum Motors – The vehicle wasn't in good condition and the seller didn't respond to my phone calls

I found the advertisement about vehicle. The company Hallum Motors responded to my questions and the staff assured me that I didn’t need to worry, because the vehicle was in good condition. Also, the seller said that he would change the tyres. I signed the contract and this company delivered the car to my address. But when I saw the car, I noticed some problems with it. The seller replied and said to call him tomorrow to discuss everything. But his phone was switched off on the next day.
