Great product, bad customer service

The sign is great. Exactly what I needed. However, customer service during the shopping experience was bad. I used the chat feature to find out about mounting hardware to mount the sign on a light pole. All I was told was - "you need to send us an email with the sign you want to purchase and a picture of where it will be mounted." That was it. Not helpful at all. I found another company that sells signs and they helped me find what I needed. And btw - SmartSign doesn't even carrying the hardware I needed.
RoadTrafficSigns: I want to apologize for the experience you’ve had with our customer service team. I’m really sorry our team was not helpful in guiding you through the order process. It’s not our usual standard. I definitely understand your concern. I look forward to providing a much better experience in the months to come.

Outstanding product and service!!

Ordered, received, and placed with the greatest of ease!! These signs are to be a reminder that it is birthing season for the deer in and around our area and placed so automobile drivers are aware of the presence of young and mothers moving in our neighborhood. Professional products and great service!!
