Pathetic/Poor Service and I bet they wont respond!

My very first time was a terrible experience, & the lady offered me a R150 voucher which I am TRYING to use. Trying to purchase something now for 2 weeks, & every time there is an issue. Firstly I used the voucher, but then my order dissapeared & voucher got used?! Then called them up as they do not respond to the email [Email Removed] , then a call centre consultant gave me a new voucher. Thinking that it is now resolved, I then use the new voucher that was given,& again ,not suprised, the voucher is invalid!Mailed a previous consultant who I had dealt with the very first time I purchased from them, & she gave the correct voucher number! I get an email saying 48 hrs until your shopping basket expires with the price etc. Now thinking I have the correct voucher, I log back on, & ofcourse my order is not there, and not only that, the price has gone up by R100, all this in one day. I then speak to the consultant again & she cant see the item I purchased,& tells me if I did not check out & prices went up they cant guarantee that prices! Not only do I have an email confirming the price,but also that its valid for 48hrs!BUT ofcourse the client is always wrong at Netflorist!
