I would like to thank the GSI team for helping my customer with a certificate

I would like to thank the GSI team for helping my customer with a certificate urgently after she misplaced her report. This helps the customer believe in the services of GSI as a brand and helps us maintain goodwill as well. Thank you, GSI, for your professional and prompt services.
