no service delivery and lack of experience

In the beginning of April I booked in my Fiat 500X for a 45000KM service, with the service I advised them of a noice on my suspension/engine. The evening when I collected my car from the dealership they advised that my brake pads and disks front needs to be replaced and seeing I have a full maintenance plan on the vehicle they will cover it. Now my car needed to return again because of stock availability, once I got in the car my service light was also not rested after the service and the inside panel at the drover door at the seatbelt was broken off. I made the dealership aware of this and they advised that they will replace it with the brakes being done. And the have also advised me that the noise I am hearing is the brake pads that needs to be replaced.

I waited 3 weeks for them to make contact with me to replace the brake disks on the car, finally when I had an appointment setup for this to take place I had one of the workshop guys driving with me in my car so he can hear the noise I complained about when the car went for the service, he then advised that it is either a shock mounting or engine mounting that is faulty and will need to be replaced. I go the car back the evening and they advised that they need to replace the engine mounting on the car as this is the cause of the noise I am hearing. Another 3-4 weeks went by without any feedback from them and out of the blue I receive a phone call stating we have received the shock mounting for your vehicle to fix the noise.

Now I am wondering if they really know what is happening with my car as first they say engine mounting and now they say shock mounting. I took the car back to them on the 23rd of may, they replaced the shock mounting that was cracked, yet car is still doing the noise, then they said it's the engine mounting. I have waited to hear from them since the 23rd of may and last week I was in the fasinaty of the dealership and thought let me stop and find out what’s happening as I am clearly not getting any service from them.

I got to the dealership finding that the service agent has left the dealership and did not do any hand over to the service manager.

Service manager advised me that she will personally get back to me regarding the engine mounting that needs to be replaced, here I am sitting still waiting a call from her, it has been 2 weeks now again with no feedback from this dealership.

Please can someone assist me as I am now fed up with this dealership and its people and empty promises.
