Business ProfileforBest of Signs

I designed and purchased a step and repeat banner from this company on April 3rd using 4 different logos. The designer revised the art but only utilized 1 of the 4 logos. I contacted customer service 3 times via chat to explain the issue but each time the proof was incorrect. Finally I was able to speak to a person and they were able to provide me with a corrected version on April 15th. During each conversation I was very clear that this product had to arrive by April 22nd and was assured that would not be an issue. On April 18th there was a status update saying that the product wouldn't arrive until April 24th, beyond the needed date. I again called the company and was told it had already been printed and that once it is printed they can not expedite shipping. If it hadn't been printed they would have charged me an additional $50 for shipping, even though it was their design team that did not pay attention to detail. It is now April 24th and the product remains in *********. The conference is today and therefore it is no longer needed. I feel they should refund my money as it was their mistakes that created the delay. They have taken no ownership to this and now our state conference is without a very important backdrop.
