Disgusting Service From NetFlorist

On Friday the 14th of June I ordered a T-Shirt on the NetFlorist Website .This was my first time ordering and I got the ****piest service ever. I had to follow them around regarding my order as the was no update on the website and I was unable to tract my order ,they took forever to respond to my e-mails.I called and spoke to some guy who was vague about the time of the delivery and told me they experiencing system problems . My order was finally delivered in the afternoon on the 15th. I was not happy with quality of the order and the size was big.I called immediately and they were already closed for the day. I called on the 16th around 9:00AM as soon as they were opened .I asked if they can rather exchange and deliver a different one same day as this was a father's day gift and they told me its not possible.I then asked for a refund as this was not going to work. The guy told me he will charge me 15% for refund. I told the guy its okay for me to understand when your systems are down and I had to follow u guys around for my order.I asked to speak to the manager. He told me the manager will call me after 15 to 20min this was at 09:38AM yesterday to be exact and I still have not received a call from the manager. I have 48 hours to return this. I did my part in calling them from the beginning. The service was so horrible and I am never buying anything from Netflorist ,right now all I want is my refund!
