Reply to Global Visa Corp promptly
I liked their efficiency. They say in their messaging that clients should keep an eye out for emails, but I had to stop for some hours mid-task. It meant they kept on reminding me to pay attention, which resulted in a flurrry of emails and I mistakenly paid twice. Perhaps they could state more firmly upfront the need for urgent replies to ensure the process goes as smoothly as possible. I appreciated their prompt reply, however, to my request for rembursement for the double payment.
