PG Glass — Rear window replacement

I contact on the 3/5/2020 PG glass Rustenburg (+[protected]) and ask for a rear window with demister for my Corolla after the Gardner damage it with a bush-cutter
They said after I pay a deposit they will order it. I went to them and pay the full amount R1750.00
On the 05/05/2020 they install the rear window. They phone later that the car is ready. When I fetched the car I noticed the window they installed was without a demister and they try to get away with it. I asked why they install the wrong window the manager said he will find out and will phone me within a hour. I phone him after a hour he said he is still trying the get the right
window. A Adel phone me later and said they cant find one because all the businesses was closed due to the lock-down and try to bribe me with R400.00, I refused and said I rather wait.
I later went to the shop. The manager said he will get the right window when the businesses is up and running. I ask him if I get one he said then we can make a plan
I find a window at Eagle glass and on the 29/05/2020 I gave PG glass the contact number. a week later I ask when can I get the glass the reply it was order and still waiting for the courier And up to now 17/7/2020 it is his excuse
On the 3 July 2020 get hold of PG glass Customer care to assist me (Jannie Niemand [protected]) He said he can help but he is successful up to now
I use the car in the morning and it is very dangerous when the window missed up and I cant see behind me. Please assist me in getting the window replaced or get my money back
