Virtual Cards and Call Service Agents.

I personally think that the Customer Service agents can be kinder, I encountered 2 seperate Customer Service agents in one day and both of the agents sounded irritated. I do not think I can post screenshots on here (which I do have as evidence). I opened a Store Card at the beginning of this month and on my Woolies app I do have a Virtual Card that I have used to make 2 seperate purchaches in store already. I tried to use it to pay my online order. When a person opens their Virtual card there is a section which you can tap on which states "How it works", it CLEARLY states "Your virtual store card can be used for in-store purchases and online purchases". When you pay with your virtual card it asks a sequence number which you can find when you "Swipe to show details" on your Virtual Card. The app stated that my sequence number was wrong 2 times. I then called customer service where I explained my situation to the agent. She told me that "You cannot purchase online with a Virtual card", I told her that my Virtual card states that I can use it for online purchases then she clearly sighed over the phone which made me irritated because I was only kind to the agent because I needed help. Jobs are scarce in South Africa, when you are blessed with one, do it with a smile because there are people who'd love to be in your working position. After I told the agent that my Woolies app tells me that I can purchase online products with my Virtual Store Card she told me (all of the sudden) "How many purchases have you made in-store", I then said that I have made two. She stated "You can only purchase online when you have made three in-store purchases". So in about 6 minutes we went from "You cannot purchase products online with your virtual card" to "You can online purchase items with your Virtual cards online when you have used it three times in store ? And if this is the case Woolies, why don't you put those rules in you "How it works" section at the Virtual Cards ? And all calls are recorded, so I would appreciate it if you would be so kind and go and listen to my call, or just to listen to how your Call Service agents talks to paying customers. Thank you so much, and do have a lovely day.
