Unprofessional service

We purchased a Ford Fiesta on 21 August 2020, we drove the car for 2 days n we informed caylee and mdu aswell as Grant of what problems we had, first of all the cars disc was expired, caylee told us she will get the disc n let u know when we can collect and bring the car in for the problem, I sent messages to caylee she would read it n not reply, bi then spoke to grant, to told us to bring the car in on Monday 31 August 2020, on our way to the dealership on Monday the car broke down, it had to be towed to the dealership, upon our arrival at the dealership grant told us he would give us a report the afternoon, neva got a call from Grant, on Tuesday I followed up n he told me the water pump went for testing he will give us a report later the day, nothing just like Monday, he then arranged a car for us to use from the dealership on Tuesday, we collected the car , just to find out that that cars had dead plugs and this cars disc expired in 2016,already, this cost us to go from jhb south all the way to edenvale n this was after we put in 300 petrol, we then went back on Wednesday just to hear the same story they waiting for a water pump report, this is now day 3, he then gave a chev spark, the disc was also expired, so today Thursday I foned grant this morning at and he tells me he just got in he will call me,, I then tried calling him the hole day until I got hold of him at2 and he said he is on his way to the garage and will call me in 10 minutes, this took another hour and me not hearing from him, I then send him a message to advise I'm going to lay a complain at the ombudsman or he must give me a another vehicle and not the Fiesta anymore and then all of a sudden I get a reply, he got a reply from the workshop and do test and he will let me know in the morning, this is every unprofessional. When we went to sign the papers every one was soooo helpful including caylee, but yesterday when I was sitting in reception she walked pass me like she has never ever seen me,
