Unhappy and Livid customer

i am completely unhappy with the service i am getting from Kingprice insurance, i was involved in a car accident on the 30th July 2019 and contacted them immediately they then assigned a person by the name of Adriaan to come tow the vehicle from the scene to a certain place around Pretoria where they store their vehicles. when i put in a claim the next day the person who was assisting me with the claim told me that they will allocate an assessor to go assess the car and i must allow them 3-5 working days, to date i haven't heard anything from them. i took the time to contact them last week Wednesday i.e. they asked for my Claims number which i provided and the lady said she will inform the person who was dealing with my claim to be in contact with me.

I made follow up today, i find a different story that they cannot locate where the car is, how is that possible when they are the ones who allocated the car to the said tow company? it is now the third week my car has not been assessed yet which might take some time of course meantime what am i supposed to be driving because their courtesy car lapses on the 30th August 2019.
