GLITCH ON SYSTEM/PROBLEM GENERATING ORDER NUMBER

I purchased goods on Spree's website on Wednesday and the one specific top I had in my bag caused a problem when trying to pay with my debit card. After numerous phone calls and speaking to 3 different people I found out it is the top causing problem. In the meantime I received a notification that the amount was reserved for my purchase at Spree. But the order number never generated on Spree's side. So I phoned again and spoke to Bukho who promised she will speak to her finance manager and get back to me, nothing to date. I phoned again later the afternoon and spoke to Leroy who promised me as well he would speak to his finance manager and phone me back before 4am. Well here we are the next day and still no reply from any of them. This is **** service Spree and I think I should just ask my bank to reverse the transaction and shop somewhere else.
