Appalling call centre, social media team even worse

So I went on the homechoice website 2 weeks a go and requested for someone to contact me as I wanted to place an order- I have an account there. Waited 2 days and no call. Tried registering online to make my purchase as no one had called me, without success. Called them last week Monday and asked to be called back, I spoke to sales agent Zimkhitha, greeted her and said "I would like to place an order and no one is calling me after I've mad a request 2 times on your website" Proceeded to give her my number and she stopped me mid-sentence and asked "why are you giving me this number, what must i do with it"? I then again explained my reason (which I already did in the beginning of my call). Her response was: "I can't we're busy". I explained to her that I wanted to make a sale, asked if she's too busy for that, and her response was yes. After this, I called customer service and told them the above, the consultant apologised, took down my number and advised that someone would call me. I have not yet received any phone call from them, I sent messages on Facebook, and yet still no response there either, yet their Facebook page says "Typically replies instantly", this is misleading and should be removed, as for their call centre, service sucks, not world class service at all. Whole service team is ridiculous. 1 week and no feedback, no follow up, TAT are ridiculous if they have any.
