terrible experience with sissyboy, worst service delivery and customer service

i ordered a pair of shoes (online) however I used the wrong email address by mistake so I reported the error on Sunday 28th JAN in hopes of a response by Monday, but no response, so I phoned sissyboy and was told that unfortunately the online department was out on lunch and will return but 13:30 and the lady had sent that department an email to get back to me, by 15:30 still no response.. so I called back but I got told sorry their lines are still busy. on Tuesday the 30th of Jan I phoned back to fix the error to which I got transferred and then the phone went to voicemail. I then sent numerous emails from the 31st of Jan back and forth about my order- the response was simply "your order is in picking from our warehouse", no response about my email address. I then phoned them on Thursday 15th FEBUARY and got told they'll change my email address (which they didn't), and that all is in order but If I haven't received my package after 15 working days I should contact them,]. So Monday the 19th FEB I email sissyboy about my order and I get response saying they cannot fulfil my order and have to refund me the money. THIS IS UNNACCEPTABLE! how can they, after 17 working days tell me this? I ordered these shoes to fly in for my overseas trip and now I HAVE TO go and look for another pair of shoes at my own cost of time and money before my trip, because of this disgustingly poor service! absolutely horrified with SISSYBOY SOUTH AFRICA
