Bi Da service is in place
When I was just sold, I didn't understand the features and advantages of the products. I often communicated with the manager in charge of my area. Here I would like to thank them for their patient guidance and answers. Usually, I often look at the data brochures sent by Bi Da or the official website to check the answers to the common problems. The communication between users is more appropriate and product characteristics. Now the sales of delta products are getting better and better.
