Netflorist disgusting service

The most unprofessional and pathetic service you could think of, firstly I placed my order for 2 items on the 26th April, scheduled for delivery today 7th May, all fine and we’ll until this morning, the day of delivery, they proceed to tell me one of the items I ordered is not in stock and they don’t know when it will be again, keeping in mind that these gifts were ordered for Mother’s Day. I then said I wanted a refund to my bank account, where as I now see they have sent a voucher, meaning I can’t try and make a plan to get something for my wife to make her FIRST Mother’s Day special, they also say refund takes 3-10 business days yet my money was taken instantly, convenient. On top of all of this, on the invoice it showed delivery fee for this product was R90, yet the voucher only refunded me R35 for delivery. Please Netflorist tell us how this happens
