Bad unacceptable Service

I purchased a pair of binoculars online on the 17th November 2018 and paid in full R1290. On the 19th November I received an email to say the item was no longer available and they needed to give me a refund and requested my bank details which I forwarded to them immediately. On the Tuesday the 20th November I sent an email through to a Celeste van der Bergh the admin lady who had been corresponding with me to ask when I can expect the refund ,she said they do them on a Wed and a Friday so I said tomorrow which was the Wed? And she said yes. On the Thursday the 21 Nov I called back as it wasn't reflecting and I spoke to A Kobie Van Zyl apparently the MD of the company to say the refund was processed on the Wed the 21 Nov but because I bank with Standard bank and they bank with ABSA it might take a day or two to reflect which I do understand. QFriday the 23rd came and it still wasn't in so I thought I'd wait until Monday so on the Monday 26th it still wasn't reflecting now it's been 5 Days since they said they had paid it I called back and spoke to Kobus Van Zyl the MD again and he was extremely rude and said there's nothing he can do it was done and will reflect that night in my account. I asked him if he could please send me proof of payment and he said he would which he didn't. On Tuesday 27 th its still not reflecting I phone and speak to Kobus again he says there nothing he can do take it up with your bank, so I said I can't if you don't send me proof of payment so he said he would that was 4 hours ago and he still hasn't sent . I honestly don't think they have paid it and it's a lot of money for me I desperately wanted to buy my husband another pair of binoculars from somewhere else for Xmas and I can't until I have received my refund. I despearately need your help please Regards Suzanne Deutschmann ********** 086
