The owner for cash crusaders runs his business on lies. Grown ass man speaks so much lies that because of him we still waiting for Jesus to come

Long story short, I needed a Huawei device to get all my stuff from the cloud cause my old Samsung s8 couldn't do that. I phoned the Richard's bay branch and said I'll buy your Huawei p40 lite if you can make a decent offer for the S8 as it's in very good condition. Manager said come in and we'll talk. At the store we all came to a conclusion he will offer R1200 for the S8. I said I don't want cash just minus it from the p40 lite. He said that's not how they do things. (very stupid system I say). He said come tomorrow cause there's no cash at the moment but take the p40 lite I'll give you my word you will get the R1200 when you come. Infront of 4 witnesses I said okay. I purchased the p40 lite, went next day to sell the s8 and Manager not in so the owner was in. Explained to him everything and he comes with R1000 offer. I said phone the manager and ask cause I'm not one those hoonga smokers that you can look down and treat bad. This same clown"the owner"twist everything that the manager said. So I went to the managers house as he lived not far from me and I asked why you speaking lies about what you offered... He said he never the owner is twisted everything around. The owner runs a business on lies and is training the staff to speak lies and manipulate us customers on buying things and we'll offer you this amount for your older ones. Seen it for myself while I was at the store.
