Pethetic service

On the 11th of February I placed an order with netflorist for Valentine's day. Payment was made on Tuesday , Wednesday afternoon I received an email to say that my proof of payment wasn't valid enough for them aswell as they told me what type of proof of payment I should present to them I sent them the correct proof of payment they send me an email to say that they cannot deliver on the 14th they postponed my deliveries for the 16th I called back and rearranged the delivery date to the 14th as I had a few products purchased from them they could only help by delivering one product on the 14th still I settled on that. Yesterday the 14th at around 3pm nothing was delivered I called after waiting for 20 minutes on the phone i speak to a guy called "Vuyo" which couldn't answer any of my questions to as where the delivery is , why it wasn't delivered or when it's going to be delivered he didn't know anything regarding the following questions.I asked for head office contact details so someone can assist me further. He said they where there head office and they couldn't even help with anything. Eventually the delivery wasn't made yesterday I called in this morning held on the phone for 25 minutes no answer I then called after 2 hours and got through only to speak to a lady to tell me that they had to much of deliveries they couldn't fit me in. I am so disappointed at this moment this is so unprofessional they will never call to inform you about anything. They can't answer your questions been "head office" they can't track your delivery or tell you when it's going to be delivered they don't even send u an email to let you know that they couldn't fulfill they promises. They advertise a wide range for Valentine's day but what's the point in delivering a day or two later when it's not Valentine's day anymore the atmosphere and the feeling is now changed and back to normal. My question to this company is that why do you guys take on so much that you can't handle why not do the bit that you can handle. You didn't just disappoint me you disappointed the recipient aswell. I will not recommend anyone to netflorist as I am very disappointed and an unsatisfied customer.
