Bad customer service

Am a CPUT student on the 27th of February 2018 , I went to Bradlows situated in Cape Town at Golden Acre to laybuy a fridge, then I was helped by a sales person called Noluvo Mgidi, l asked her if is their delivery free or what ,Then she told me it's not and I should pay R500 extra for delivery or she will organise one for me which will cost me R300. Then I told her no it's fine I will organise my own transport because I cannot afford to pay R500 nor R300 from CBD to Woodstock ,then she said it's fine.

So today (31/03/2018) I went back there to pay the outstanding balance and collect my fridge, then the lady told me that I have to go and fetch the fridge at their warehouse they can't give me from the store and which was new news to me I knew nothing about it , so i asked them why and i was told it's how they do it, but at first when I told the sales lady that I will bring my own transport never told that I will have to go the warehouse and fetch the fridge there by myself. so the manager told me that I should have paid the extra R500 and they would have delivered the fridge instead of bringing my own transport, so you should go to the warehouse and fetch the fridge . So I don't understand why should I go to Belleville at their warehouse as the customer to fetch my own fridge and when I first purchased it I was never told that if I have my transport i will have to fetch it myself at their warehouse, instead of explaining it to me the sales person was rude and also the manager too.

And worse part of all the sales person told me to lie about where am I taking the fridge so that maybe the manager can give me the one in store.
