Bad communication with nedbank car insurance

My husbands car was involved in an accident on the 3rd of march,it took nedbank car insurance more than two weeks to verify our information and give us excess fee amount,the car eventually went in thier garage on the 31 of march 2025 up until today the 24th of april car is not done,no communication from nedbank we have to make calls by ourselves everytime to the garage the worst part is that the car of the 3rd party is still with the owner he must use with a broken windo while waiting on nedbank car insurance..such a bad experience we are having with them, so many delays that are costing us..claim number ***1
