I only signed up for the card because Amazon provided an incentive. I did not realise that I had bought an item for it. I asked for the late payment to be waived and that I will pay for the balance in full afterwards. I did not receive any response whatsoever and instead was slapped in the face for another 5 quid.
I have paid my balance in full now reluctantly as I want to get as far away from them as possible and not deal with this toxicity.
Stay clear of this awful scammers and their credit cards.
