The manager told me that i won't get credit again because im pregnant.

I was served a very raw deal by Lewis Rustenburg, im a pregnant woman 9months months now, last month 24 june 2022 i bought a bed, a fridge and washing machine from a Lewis store on credit, when the fridge was delivered it had a dent on it, i called the store to inform them and also that that is. Not the fridge i wanted, i was told the manager will contact me to this day the manager hasn't. I called customer service and they also said they will call me back even today. I told them i do not want the fridge anyei. Want to exchange for a smaller one and kitchen unit. The rude manager told me that he is new he knows nothing and he has to cancel the whole deal and i might not get the same credit or no credit at all. He told me that i can write complaints to the ombudsman and every one it doesn't matter because they get complaints every day so he will cancel my contract and collect everything i bought. I asked him what must i do as i wont have a bed when he does and im due to give birth he told me its not his problem. The said refrigerator has been standing for a month now and now that its month end they want me to pay they came with the same fridge i said i did not want and the manager did not call me i am the one that had to call again. Please help me im so frustrated and dont know wt to do. The manager blatantly told me that i wont get credit once they cancel everything to redo it because im on maternity leave, such level of **************
