Iwyze claim experience

My car was involved in an accident on the ~23/04/2023 and a claim was registered and approved on the 18/05/2023, since then my car had gone for repairs, is been back and forth with the repairer and the insurance, at some point the repairer indicated that the car is ready for collection and upon collecting the car i was shocked as 60% of the damages were not repaired and i am referring to the obvious damages,visible damages which dosent need a specialist to see them and i have logged a complaint with the insurance and the matter was just treated as normal and additionals were loaded to repair what i complained about, and till to date i haven’t received the car, im being told that it is ready for collection and when im supposed to collect it then they inform me that something is still missing or they waiting for parts. Bare in mind i have been with the insurance since 2015 and this is the kind of treatment i am getting from this insurance. Im sending emails daily and weekly the only reply whenever it suit them.
