bad service

Can Nedbank please sent me my monthly statements. I keep paying my credit card. They keep phone and ask for another payment, stated that they never received my payments and every time I just need to make a payment. They phone 2 weeks ago stated that I need to pay R420, which I did. They just keep on calling and calling, know I own over the R600. I could never used the app, I had login problems, I haven't use the card because their was pin issue and they was supposed to sent a new card, which I never received. I keep asking for statements which I never received not even one. I have been paying from 2019 the credit card, with no statement, I do not know how much I own, what my monthly installment is, and if I am paying the man on the moon every month. They phone every single day, even at night. I am done taking any Nedbank calls, I am done paying. Please provide me with statements on my account since I opened it in 2019. I requested statement with every call. No statement, no payment.
