Bad customer service

So I contacted this unprofessional company to find out how much they will offer for my new lounge suite that hasn’t been used because we bought two, not only did they read the message and not answer, I also had to beg them to reply and when they did reply they spoke to me with sin an attitude and so much to sarcasm, they offered me R800 as an insult for my stuff. You know I understand if you don’t want to purchase something from someone and that is absolutely fine because we all have different taste but to be so rude and mock me but offering me R800 for something I paid R26,000 for, and I wasn’t even asking for that much all wanted was to know if they were interested because the internet said they are the best, but that was such a lie, this company is an absolute joke and I urge anyone who has stuff to sell NEVER EVER EVER go to this company because they will only make you a fool like they did with me. It’s so sad to see so many people in a company act to horrible towards a potential client/customer, this company should be closed due to its unprofessional manner of chatting to clients and to make things worse it was their WhatsApp line that answered me like that, I mean can you even be so brave to do that to someone you don’t know who could possibly be one the greatest clients your company could ever have, I could of been that client. It’s sad to say but this company won’t last long due To its employees and the was they act, imagine people lower than you acting as if you owe them something lol this has to be a joke, no one should support this company
