Service disappointing

I bought a car about 10 days ago, on the day I drove out the velve of the tyre was broken and the car making funny noises I contacted the sales person, I was also informed my new plate numbers will be sent within 7 days and I have not received any correspondence. I have not received the contract and someone called me and said they will get someone to call me and no communication. If I were to compare we buy cars and weelee, we buy cars offers much better service than what I have received. I am really disappointed ☹️ and I wanted to give them the benefit of the doubt however I am disappointed
