Poor Service and Lack of Assistance with Voucher Withdrawal Since March 31st

Since March 31st, I have been attempting to receive assistance with a voucher withdrawal that is not showing in my 1Voucher app. Unfortunately, I have been assigned inad agents who only ask three basic questions (regarding the query, my cellphone number, and the serial number), and then disappear. Offering no further assistance they become unresponsive. This has been the most dreadful service experience I have ever encountered
