Door latch/lock after accident not repaired

Budget insurance was very helpful with my claim, everything went well with the repair centre. My only issue now is that I have been trying to get hold of them (to no avail), to request that they do something with my door latch which is very loose after the accident.I did mention this prior to the repair centre fixing my car, the repair centre even went as far as checking to see if they can assist but now its loose again. Please do look onto this
