Nedbank GreenBacks nightmare

I've had a Nedbank credit card since 2017, and have been collecting GreenBacks since then. I have a Nedbank GreenBacks card, which works like a debit card, and you are able to spend your GreenBacks like cash.

I've attempted to use the card on several occasions, it has never worked. Recently, I attempted to use the card online to pay an account. Again, the card did not work. This time however, Greenbacks were deducted off the balance, even though the payment was not successful.

I have raised a complaint with Nedbank to activate the card so that it can be used. I also raised a complaint that GreenBacks were deducted from my balance even though the card is not functional for any payments.

Feedback received was that both issues were resolved, and the complaint was closed.

I'm not sure what was done, if anything. I've tried to used the card again, and it definitely is not working. My GreenBacks that disappeared have also not been re-instated.

It does not appear that Nedbank knows what the issue is with the card. Perhaps they should just issue me with a new one if they cannot get the current one to work? Also, if GreenBacks are deducted from my balance incorrectly, I would expect them to be re-instated with immediate effect.

I am extremely dissatisfied with the level of service that I have received.
