Bad customer service

Yesterday the 19 may 2020 my wife went to bradlows promenade mall ( after I called the store earlier and asked about the items that I wanted to buy and I specifically asked how long does it take for them to deliver) to purchase furniture worth 20k she was told that the delivery will be done the same day or the latest 20th. We called on the 20th around 12 o'clock asking what's the hold up with the delivery because we have been waiting for them since this morning they said the delivery takes up to 3 days of which they never said that in the initial stages then when I spoke to the bradlows manager about this complaint she said the same thing and I explained my side of the and that on the 19th when I called the store to ask about the items plus the delivery process I left everything and sacrificed my lunch hour because I knew that I was going to a funeral in eastern cape on Thursday the 21st, the manager then said she was going to call me back she first needs to speak to the consultant who was assisting me. She never called me back and whenever I called the store they said she was busy about 2 hours later I received a call from from the consultant who was assisting me the previous day she had to come from home as she was off today to call me meanwhile the manager was there acting busy or my complaint was not important to her?? As a result this has left a bitter taste in my mouth regarding your brand
