BAD SERVICE AND FAULTY WINDOW

I LODGED A CLAIM FOR MY WINDOW AFTER AFTER A SMASH AND GRAB INCIDENT. FIRSTLY IT TOKE OVER 2 DAYS TO GET AUTHORISATION. FINALLY IT WAS AUTHORISED AND THEN TOKE OVER 3 DAYS FOR THE PART TO BE LOCATED ONLY TO FIND THAT THE DELAY WAS BECAUSE THE CONSULTANT I SPOKE TO GOT THE VIN NUMBER WORNG. I CALLED NUMEROUS TIMES AND EVENTUALLY A LADY BY THE NAME OF THATO ASSISTED ME. THE MOBILE UNIT WAS SENT TO FOX MY WINDOW, THEY WERE LATE AND ARRIVED IN THE EVENING AND PROCEEDED TO WORK ON MY CAR IN THE DARK. I WAS TOLD NOT TO TOUCH THE WINDOW FOR 48 HOURS THEREAFTER I MUST TAKE IT TO THE FITMENT CENTRE TO GET ANTI SMASH AND GRAB FILM PUT ON. WHEN I ARRIVED AT THE FITMENT CENTRE THE GENTLEMEN FIXING WORKING ON THE CAR TOLD ME THE THE PREVIOUS GUYS DID NOT PUT THE WINDOW IN PROPERLY (THEY DID NOT SPRAY IT) AND AS RESULT THE WINDOW WAS COMING DOWN WITH THE RUBBER! HE ATTEMPTED TO FIX IT AND IT DIDNT WORK. HE REFERRED ME BACK TO THE MOBILE UNIT WHO I CALLED 2 DAYS AGO AND SAID THEY WOULD COME BACK TO ME AND THEY HAVE NOT. I DO NOT UNDERSTAND HOW IT CAN BE SO DIFFICULT TO RESOLVE THIS. IT HAS BEEN 2 WEEKS SINCE THE INCIDENT AND I AM SITTING WITH A FAULTY WINDOW. THIS IS RIDICULOUS
