BannerBuzz review: They will NOT deliver your merchandise on time as promised

I placed an order for window decal and paid for priority shipping which means I was supposed to get "quick" turnaround. I uploaded the artwork and asked for the proof, supposedly a proof was going to be provided in a few hours. They provided me with the proof about 7 hours later but instead of my image they took out the color from my artwork and made it all white. I asked their design team to make the decal look exactly like the picture I uploaded for them. The next day, I was waiting for my proof, I gave them 8 hours, and nobody got back to me. I contacted customer service to find out what is going on with my proof. Customer service told me that their design team is overwhelmed and asked me if I could wait another 2 hours. I told them ok - 2 hours later - there was nothing from their design team. I contacted customer service and they gave me the same story - they short staffed and they are working on my proof. Make long story short - I was going back and forth with them for 2 more days. Now - 3 days later they finally provided me with the decal with correct colors, but the shape is all wrong. There was a reason why I paid extra for priority handling and processing - and what did they do - waste 3 days due to their incompetence, and to add insult to injury, they told me that I have to pay $20 more to get my order processed and shipped. I DO NOT RECOMMEND THIS COMPANY - STAY AWAY FROM THEM, YOU WILL WASTE YOUR TIME AND MONEY!
