Furniture liquidation horror with how staff member handle issues.

I would give 0 if possible. I bought two single beds on the 24/12/2024 which were paid in full. The lady who made the sales called on the 30/12/2024 saying they gave me a wrong order and she only noticed it now when they were doing stock check. I didn't have a problem in exchanging the beds I mentioned that I am at work at the moment and thus can be done when I am off. I also mentioned that no furniture movement was allowed after 18:00 in the complex I stay in. She kept on harassing me with none ending calls. She wanted me to buy the balance of the wrong bed given. She was rude and never wanted to listen to what I said. But wanted to do things her way. With the consumer law any mattress bought and used can't be returned. She then came with the police to my complex. The unprofessionalism this matter is handled with the attitude given. Yet I was willing to meet her halfway by returning the other used bed.
