Delay and lack of communication

I am not a happy client at all. I had an accident on the 20/10/2018 and the car was towed to SMD the same day after I called King Price Insurance. On the 22/10/2018 I app**** for a claim for the car to be assessed for the damages occurred and my claim approved on the 2/10/2018. I had no problem with my insurance because everything was running smoothly and communication was at it best, I would even receive massages every morning from them. I was told that my claim has been approved and the car will be taken to panel beater Auto Spray on the 3/10/2018, I was also told that the Maria from Auto Spray will be in contact with me soon to brief me with the update. From the moment the car was taken to the panel beater I haven't heard from them until I called the person that was assisting me with my claim Maletsatsi on which it was on the 8/10/18, that's when she told me that Maria will be in contact with me that day and told me that the parts has been ordered from the panel beater, but I haven't heard anything from Maria even that day. Maletsatsi sent me an email with Maria's contact no, that's when I called Maria on the 9/10/18. Maria told me that they are still waiting for other parts to be delivered, but most probably if I didn't call she wouldn't have been in contact with me. From there ever since I am the one who has been calling Maria to update me about the car. She will tell me that she will call me back but I wouldn't hear from her. last week Thursday I was told that the car is almost ready and it has been taken for polishing. I was exited and even paid the access fee of R13 000, To my surprise! yesterday I called and they told me they are still assembling other parts, I asked them how can the car be polished and assemble the parts after, I was told they missed a spot. After that I get a call to tell me that the exhaust still need to be fixed and they still need to get someone to come and fix it. This is the fourth week now and I bought the car for reason most especially that I knock off late at night and I spend too much on public transport. Is this the way should thing be because I don't understand you procedures at all as a client.
