Ignored, yelled at, not provided with the products bought

Ordered from this company before and products arrived quickly and correctly. Sent an enquiry via the webform and email to request info about a product. Never received a response. Ordered more items last week and the order status remained Unfulfilled for a week. I sent enquiries about my order via web form and email. No response. Sent a WhatsApp text. No response. Sent another email. No response. Tried to call via Whatsapp on the number supp**** on the website. No answer. Tried to call the same number via regular call. No answer. Eventually, I used the review section of one of the products I ordered to comment and beg for someone to contact me about my (fully paid) order because I couldn't think of any other way to be heard. Suddenly the owner calls me from another number and admits that her "staff" completely missed my order - for over a week. And now the main product I ordered is out of stock because the stock that was available when I placed my order was given to people who ordered after me. She was full of excuses for not replying to my multiple enquiries (this time - but couldn't answer when I asked about being ignored previously) but eventually offered either a refund or other items for the amount owing due to my items being sold to other people. I asked for more of another product in its place. She then kept saying she'd refund that amount and send the other items. I repeated what I had already asked (it wouldn't cost her anything extra - in fact, it was less in the pack for the same amount so I'd be the one getting less) and she just kept talking over me about the refund. I had to raise my voice to be heard over her and repeated a THIRD time what I wanted to be done with MY money. I even had to ask her if she'd heard my reply and she said no. So I had to ask AGAIN. Then she told me to not yell at her if I was having a bad day. I wasn't the one yelling and ignoring a paying customer. I didn't make the mistake. I didn't fail to provide feedback. I didn't ignore anyone or refuse to listen to anyone. Eventually, I couldn't take her squawking anymore so I just said that I wanted the items by tomorrow or I would take this further, and hung up on her. Then I received a text from her saying that she was ignoring my request and refunding me instead because she gets to make the decision. Now she expects me to wait until whenever she decides to do the refund and then wait for it to clear back into my bank account before I can use that to order from someone else - after I've already run out of the products due to her mistake wasting over a week of my time!!! This is absolutely ridiculous and an utterly appalling way to conduct business. If someone had simply contacted me or rep**** to any of my numerous attempts to find out what was going on, and provided the requested replacement products as a matter of priority for messing me around for over a week, this could've been rectified without this being necessary. I don't mind if a business makes a mistake, but how they handle their mistake tells me EVERYTHING. And this could not have been handled worse.
