Savings account nightmare

I opened 1 savings account online in February to my surprise 2 bank cards were delivered to me and I decided to check on the banks app and realised 2 of the same type of accounts were opened. Since then I’ve been trying to call Nedbank to sort out the issue but the call centre agents keep taking me back and forth, I remember Emmanuel and Minenhle because I spoke to them on more than 1 occasion and they promised to resolve it but nothing was done. I am so livid because Nedbank keeps sending me emails about the account being in arrears and lying that they keep contacting me to resolve it but not even once did they call me. I am the one who keeps calling in and trying to remove the second account because I am scared to use any because it could be a *****ulent account and if I lose money nobody will reimburse me. I regret ever opening an account and I will never recommend this bank to anybody. They want to digitalise things but they are failing dismally at it and their customer services are horrible. All they know is sending threats pertaining to my credit, I really do not care because I’m not gonna pay for an account I didn’t open and I am not even sure how it came about and they are failing to assist me in closing that second account and at this point I don’t want any account with them, I’ll gladly find another bank that is customer friendly. They don’t even deserve 1 star.
