Despite the high rental fee we paid, the booth's location was not prominent enough, which resulted in a lower turnout than expected. We were hoping to attract more visitors and generate more leads for our business, but we did not receive as much attention as we had anticipated. Furthermore, I was disappointed with the behavior of some of the on-site staff. Based on the online reviews we received, some visitors reported that they were not very helpful and lacked enthusiasm. Additionally, there was an incident where one of our visitors had an argument with one of the staff members. Thankfully, one of our employees intervened and prevented the situation from escalating further.  As a company that values customer service, we expected better support from your team. We believe that the experience could have been much better with more attentive and helpful staff. We would like to request a partial refund of our rental fee due to the issues we faced during the exhibition. Despite the negative experience, we appreciate the opportunity to participate in the expo and showcase our products and services. We hope that you will take our feedback into consideration and make improvements to enhance the overall experience for all exhibitors and visitors. Thank you for your attention to this matter. Sincerely, Tracy Washington Chief Executive Officer, Super-Ice Tech
