For that, we hope you could accept our sincere apologies here and would greatly appreciate it if you could point them out to us either through email [sales@yellowreef.com]. In our continuous and relentless pursuit of excellence, we would like to extend a very small token of appreciation to you for these selfless feedbacks (per mistake reported and accepted).
