Mom's 85th birthday delivery NOT delivered

I ordered a hamper for my mom's 85th birthday, 2 days ahead. I am in Jo'burg and she's in PMB, KZN, so it was important, as I couldn't be there. An email from NetFlorist confirmed delivery for her special day. Now, four (4) days AFTER, there is still NO DELIVERY! I contacted them on the delivery date to complain and got an auto-response, saying someone would be in touch. They haven't been, at all. I called them twice today to follow up, at my expense. Lots of excuses later, all I've been offered is a refund on the delivery fee. It's no good enough. My elderly mom thinks I dis-regarded her important birthday. I am stressed out about having used a company that USED to be reliable and no longer is. No communication from them. SHAME on you NetFlorist, this is the last time I use you.
