Netflorist Disappointed Customer

My son and daughter both finished final exams on Tuesday (one in University and one in Matric). On the 25th November i placed two orders from Netflorist (personalised items) for delivery on Wednesday , 27th November. I made my payments with immediate release which my bank charges me for and sent the proof of payments for both orders straight off my banking app to the contact details on the order confirmation. Yesterday i did not hear anything from Netflorist and sent them an e-mail to ***,za. I received an automated response telling me they would get to my e-mail. This morning since it is the delivery day of my order i chose to call them. The agent told me that the orders are on hold due to payment not being received , nonetheless as a frustrated customer i then resent my proof of payments directly to his e-mail address. Upon his return from his finance department i was told that the finance team do not check the payments they rely on proof of payment to which i added was sent to them on the 25th November already. Cutting the long argument story short , i have now been told that the order can only be delivered on Saturday , 30 November 2019 and one item from the order can only be delivered on Monday , 02 December 2019. I am very unhappy about this because the reason we send gifts and the days we choose to send it from the website calendar is significant to the occasion. The payments go through quick enough but the delivery then becomes the problem which is false advertising from netflorist on making someone's day and making them smile. I am extremely disappointed and unhappy with netflorist.
