"Supervisor! This client has a voucher and I don't know what to do."

I just spent 14 minutes and 30 seconds on hold with checkers sixty60 after going through the entire app, trying their online help, AND their whatsapp line to get a simple answer to a question that should not even exist. HOW DO I LOAD A VOUCHER CODE ONTO MY APP so that I can place an order? This is absolutely ridiculous. I demand my money back for airtime. And as an entrepreneur, I don't just get paid for showing up - I get paid for work done. While sitting on the stupid phone while someone is "on lunch" for 15 minutes, I'm losing out on money, which makes the voucher worthless. What is this country coming to??
