How to fail in business - complaint number 2

I placed an order last week on 3 May 2018, for 2 steel cabinets. Nowhere in the quote did it say it would take 6 weeks for delivery. Today I phoned to enquire when my order would be delivered and I was told 28 June 2018. Six weeks for a cupboard that is available at Makro or Builders for an extra R300. Ridiculous. When I told the dear lady who answered the phone (of course names are not given) that I wanted to cancel my order, she said the refund would only be processed in 2 weeks i.e. they only make refund payments every second Friday. In this day and age of instant, internet banking. I asked to speak to a Manager only to be told that he is out. I then told the dear lady that I would send a letter requesting cancellation of my order and immediate refund and if I did not get it I would report them in this medium and through the Star Consumer section. She told me that if I do that I "can kiss my refund goodbye". Really? With the Consumer Protection Act in place? I agree with the other complainant's headline for this business "How to fail in business". I am only surprised they have not failed sooner.
