Discovery Insure - Generic Windscreen instead of original???

My windscreen cracked 3 months ago and i clamed soon there after. I was told that someone would come to my house and replace the glass which i was excited about. I setup a date and they arrived. WITH A GENERIC glass. I pay my monthly premiums for an Audi coded glass and NOT a generic. I have waited patiently for this matter to be resolved with no luck. I have waited for a month without any news. Manasseh (The Manager) sent me an email on 6th November saying she tried to contact me. I was unfortunately in a meeting at the time and so could not take her call. I emailed her back asking for her to contact me and she hasn't. Today i was put on hold for 32 minutes waiting for some clarity and acconowledgement that my glass would be replaced with audi glass but received a message from Jade that Manasseh was in a meeting along with her manager Musa Dlico. I am reaching out for help and want to know if anyone else has received such utter pathetic service from Discovery Insure, a company I have been a client of for years with no claims and now when claiming for a windshield i get this trouble. I am very disappointed and hope for this matter to be resolved as soon as possible as i am riding around with a cracked windshield which is not SAFE. Please HELP me ASAP
