Worst customer service ever

Yesterday I was at Checkers Heiderand, Mossel Bay Mall, where I spend a ridiculous amount of money on groceries. I asked the cashier to provide me with a Checkers Xtra Savings card, but was told that the store didn't have any cards left. I then had to used my friend's card. Today I need to make a purchase online, but couldn't sign up, as the system doesn't accept the details, using my friend's card. I therefore phoned Checkers' "toll free number", but was told to get my own card. I explained to the consultant that I live 55 kilometres away from the closest Checkers, that I couldn't get a Xtra Savings card yesterday, and that I urgently need to make a purchase online for someone in Cape Town. The person first explained that I cannot make any purchase online, that I had to download the app onto my phone. When I enquired about the card, he said that I must get my own card, that I can't use my friends Xtra Savings card. When I explained the situation again, he ended the call on his side. I'm therefore not very happy about the type of customer service received at Checkers Heiderand nor from Checkers' toll free number.
