UNHAPPY CUSTOMER

I'm not happy with the service from Renault Alberton Beginning of September I ordered a window and Paid R2970 to order the window, I was told it was going to take 30 days to get the window,I waited and no Communication whatsoever,then I went Month end of September I was told it was supposed to be delivered on the 20th of September but it did not come,and that I should give them another 20 days which I did, now going back without communication I am told there is no stock the supply has not responded,so now I fill up forms and submit documents for my Refund,which I am told it takes about 3 days,I ask the consultant to tell me when the the refund was processed,he sait it was done last week Wednesday which was on the 19/10/2022, so today I am being told for the refund to be processed they need to cancel the order and submitt documents to accounts and then they can process the refund,my question is was nt that supposed to be done on Wednesday?I have an emergence I need my refund Today not the Useless excuse they telling me
