Peugeot - One and a half month later and I still don't have my car window

I regret the day I bought a Peugeot. My claim from insurance got approved on the 2nd of November 2018. Today it’s the 12 of December and I STILL don’t have my window fixed. They’ve moved the ETA dates more than 5 times already. I even escalated Peugeot Hatfield and I got a call to say I must go to Glassfit Centurion to have the window fitted, only to find that Peugeot delivered the incorrect glass even though it says on the order they should bring the left rear window. The worst part is you can tell they don’t care about my issue. My calls have been ignored by the Hatfield branch when I want to talk to Pheneus ( The guy who is supposed to order the window). The last time I called him he said: “Well you’ve escalated me to head office so they should tell you when you going to get your window”. I have literally given up. Head office pretended to capture my query. I had to call after 3 days as they had promised to call me within 24 hours. When I called they didn’t even know what I was talking about, so I had to re-log this complaint. I have even given up on chasing them. NEVER BUY A PEUGEOT, NEVER. I am so fed up I’m even trading in this car as soon as the window is fixed
