Pathetic customer service

I'm battling to get my R4000 refund for an online auction vehicle purchase. What started as a great deal, has now turned out to be a nightmare. I've been to their main branch at The Dome. My sales rep, Lebo Ramashala is now ignoring my calls, texts and emails. In an attempt to get assistance, I then got hold of Zander B, who also promised to assist. Guess what, he's also just like his colleague Lebo. I then went there for the 5th time, spoke to Os Maluleke, who also acted concerned about my frustrations. Guess what, he's just as not helpful as his colleagues. They're all ignoring emails and texts. So much for trusting them. If they were working for me, they'd all.be fired for lies, empty promises and dishonesty to customers. This is the thanks I get for doing business with WeBuyCars and Lebo in particular. How I wish it was possible for the vehicle to be returned and be paid back the money spent on it. A bunch of ****s. Can someone senior please look into my query. It's been over 3 weeks of pure frustrations and listening to all sorts of excuses from your unrealiable employees. I've given them everything that they asked for. Bank statements, bank confirmation letter, id copy, Proforma, my time and hope. All the efforts for what? I have probably spent half of the R4000 refund on fuel and cellphone costs, in an attempt to get it back. I hope someone who really prides themselves in customer care will make the right decision in ensuring that my query is attended to and gets resolved.
