WAEPLUS didn't deliver my order and can't tell me when they'll have it back in stock Birmingham, Other

Never again:

Very bad experience.

I placed my order on 13th of March, was quoted 4-6 business days delivery. Money were taken from my account the same day. Before placing an order I called waeplus to confirm that they have it in stock, and they did. I also called them a few days after that to see if they still have it in stock and if my order has been shipped. I was told that it's in process. When my order didn't arrive on the 21st of March the latest as it was promised I called them again to figure out what's happening. I was told that they are having some problems with my order and that it will be delivered by the end of next week. I asked customer support officer what kinda problems exactly are they having and no matter how hard I tried I couldn't get an answer out of them, all I got was that it was a problem on their side and they assured me that I'll get it by the end of next week (which is 25-th - 28th of March). So what a fool I was to believe it. On the 23rd of March I used their fast response contact, since they work only on weekdays, I expected to get a reply on Monday or Tuesday morning but nobody contacted me. So I called them today again, I spent 20+ minutes on hold and while waiting I checked my order status online and what I found was that "This order is marked as Stocking Issues". I must note that since I placed my order I checked status online everyday, and it said awaiting fulfilment and today I get this. WTF???!!! As I already said they had in stock when I placed my order and they even had it on 22nd of March. But now it's gone. Ok, back to today's conversation with customer support, at first I was told that they'll have in stock next week, when I asked if she's sure about it, she said that not really and she can't tell me when it will be back in stock. I asked for manager or someone from logistics department and was told that they'll tell me same thing, I kept insisting but still didn't get contacts info. Finally I convinced her to email me saying that once they have it in stock it will be shipped to me. In this email I was also offered to get an alternative from them or a refund.
I decided to wait a few more days but I still would like to speak to someone from management or logistics department.

Overall terrible retailer, I wish I ordered this item from amazon even tho it would cost me a bit more.
