Terrible service and workmanship

I am extremely unhappy with this company. Recommend by my body corporate probably because they cheap. They installed a double glazed front door which opens on the inside of the house. It constantly lets water into my house and keeps dropping down and damaging the frame. They have been back on multiple occasions to resolve the issues but seem unable to fix it. They promise to arrive at certain times and dont pitch, not even a message or to say say they not coming. They promised me a rubber seal, 3 months now and the repeated excuse is no stock available??

I deeply regret having to deal with CPT aluminium. I will be getting another company to replace the door who does a proper job.
