Worst decision of our building experience to chose AMBASSADOR doors and windows in Caoe Town as a supplier

I bought R288 000 worth of windows and doors form Ambassador Doors and Windows. When I collected the doors and windows everything was bubble wrapped. Off Load it at my house and as we offload it I saw scratches on my door. I reported it and Wesley phoned me and I drove the 90km from my house in Herm**** to Ambassador in the Cape, after they said I can come and get some touch up paint.

As the builder installs the windows he showed me the 2 sliding windows are very very skew. And Ambassador never drilled the holes/place that the lock and pins need to go into the frame of the opposite sliding window. I also was not supp**** with the inserts that needs to be pop-riveted into the opposite frames. So I phone Wesley on the 13th of August and he said they will come and fix it. I did stressed that my house is now open because that windows cant lock. We agreed I will fit the door also and then he will send a team to check everything. So they installed the front door - same scenario. There are no holes for me to be able to lock the door. And it appears the lock is the wrong way around. It will be able to lock from the outside but not the inside. Hole drill outside not inside. I let Wesley know and asked him to come and sort out the front door and windows that can't lock. That was on the 18 of September. Then I Whattsapp him on the 19th to hear when they can come and fix their mess. My house stand is standing open. Wesley does not answer the whatsapp. Monday The 21 September - again Wesley has no reply. Tuesday I get through but it is some body else phone. He is busy He WhatsApp and phoned I can do the work myself. I said I can try but were are the inserts? No answer. From the 18th of September. I don't get a answer from Wesley. I Phoned and they said they'll make a plan. Phoned again today - 29 September and I keep on stressing I cant lock my front door and my windows. Keep on getting promises about them phoning back. Had a Aluminum Door installer today to come and fix the mess. He has to order the inserts and my door will be a mess because he doesn't understand how they installed the lock wrong way around. On top of that he actually doesn't want to touch the door because then it is his mess not Ambassador's anymore. I am very disappointed with their after service. The moment the door and windows were out of their store, and the R288 000 was in their bank account, I have been left with the problems that are theirs to fix. They have no after service and I am left utterly frustrated.
