Terrible Customer Service

I just placed an order for just over R1000.00 with netflorist, immediately a pop up comes up with a 10% discount on my next order with a link to place this next order, i thought that it was a great gesture, so i clicked the link (thinking that i will be getting this 10% discount), only to find that it didn't capture the 10% discount.

i called the net florist customer care and shared my frustration with a lady called "DEANDRE" (the spelling might not be correct) and she told me there's nothing that they can do as it was a pop up, i expressed to her that this is not the first time im purchasing from net florist and i just spent an order of just over R1000.00 please could she call her manager, she tells me her manager is in a meeting na puts me through to another agent who tells me the same thing. I've cancelled my second order based on this terrible customer service, i will definitely not use netflorist in the future.

just a side note - if you listen to the recordings you will here this agent tell me that she does not know what to do, instead of taking my details down and getting someone to call me, she says she doesn't know what to do. what a joke.
