No delivery, no feedback, unpleasant staff

On 13 June, I placed an order for two cupboards. The seller is BLUESALLEYTRADING. Delivery was supposed to take place on 23 June. On 24 June, I called and spoke to a customer service agent, who gave me a reference number (after I asked), but nothing further has happened, and there is no progress on my order when I check the tracking function. Today, I first tried the WhatsApp line, without success, and then wrote an email to customer services, asking whether the order would still be carried out. It is for a substantial amount of money, and I am not impressed with the fact that there has not been any feedback. I then received a phone call from the rudest agent I have ever spoken to. Please note, I am not an idiot, and I do not appreciate nor deserve to be treated like a child when I am not the one at fault. She told me there's nothing Makro can do, and when I queried that, was told 'I keep telling you...' at which point I put the phone down, otherwise I might have been less than polite in my reply. Kindly follow up on my order ASAP, and train your customer service staff better. Since this is my second disappointing experience with Makro, I will not use your online service again. Thank goodness you have a lot of competitors.
