Bad service

I opened the account in 2019 and since then, Tymebank smartshopper never worked. I was assisted by the store Tymebank agent, failed, Tymebank call center failed. They referred me to Pick n pay, they failed and referred me back to Tymebank. I referred a friend to open the account with Tymebank and their smartshopper also doesn't work and the store agent also failed to resolve it. My card will expire next month and I see no need to renew it because it doesn't give me any points.
