WORST SERVICE AND SYSTEM IN THE WORDL

So i have a new credit card. When i called end August they said first payment due end Sept. I called mid September and they confirmed. I called again 30 September to ask why has not gone off. They said no debit order set up and this after I confirmed 3x. I then asked and they said they have now set up the debit order but I must do manual payment. They gave me 2 methods and none worked. Called again and eventually did payment through app. I got a notification that my account has been blocked. When I called again on 3rd, held on for 21minutes she said it will take 72 hours. She said I would get reference number as it will be escalated but call just dropped. HOW *********** CAN YOU GET?? I want a written apology and a phone call!!
