i want my money back! Decofurn is a bunch of *********** *****!

I am in absolute disgust with the way Decofurn Springfield Park has treated me. I had purchased a 3 piece recliner set from them which was initially stated to be selling at R15999, the sales lady named Rumba advised me 5 minutes later that it was actually selling for R14999, she loaded the sale on her tablet and sent us to the cashier. When we got there, the cashier said that the items did not appear on the system and the sales assistant had to come back to redo the order via the tablet. She did it in front of the cashier who also seemed to be annoyed with the fact that the sales lady was so ***********. Once the items were processed the total on the system calculated to R13480, i asked the cashier if that was the right thing that was loaded and she said yes, and repeated our order in detail. We paid for the items and left. About 30 minutes later the sales lady Rumba called me to say that we paid the incorrect amount and that i need to come back to the store and pay R1000 more. I was driving at the time and so i told her that i am unable to come back there. She told me she will send me a link to do an immediate payment. She called me back again and stated that she made a mistake and that i needed to pay R2000. At this point i was highly frustrated, because i was given so many different pieces of information. Her excuse was that it was a human error, one person to make 4 mistakes???? She also advised that the range was discontinued with that suppler and that they don't have that stock, they have newer stock. But when i was in the store, she told me that they only had 4 more in stock. It is not my duty to know who their supplier is. What was on the system is clearly what i was supposed to pay. When i called to speak to the manager Baboo he stated that he doesn't know what was happening and that i must speak to the sales lady. What kind of manager is not aware of what is going on in his own store? When i read my proof of purchase it clearly shows what i paid for and how much each item was, so how can it be the wrong stock? To top it all both the sales lady and manager were both extremely rude. They were speaking over me during our conversations and raising their voices, This is no way to speak to your clients. As a consumer i know my rights. Had i paid for the items and taken it home same time, would they have called me back to pay any extra money? No! So i want my R2000 back, that they demanded i pay. I believe that i was ******, so that they can milk more money from their customers. Decofurn needs to also look at the type of staff they hire and allow to manage people. They are a bunch of *********** people. When i had my legal representative call them, they **** to her about the entire story. All they talk is lies. I will never do business with this company again, and looking by all these comments posted, they don't care about what their customers feel or want.
