NRB are ****S

I wish there was a no star option available. NRB are a bunch of ****s, My account with African Bank was incorrectly handed over to NRB as there was a monthly debit order in place at the time of my supposed hand over to NRB, 2 MONTHS after my last installment was paid to NRB, my acount with African Bank was paid up for which I do have paid up letters, now going on 4 years later I am STILL being harassed by NRB for a collections payment which I do NOT owe them as they had NO HAND in collecting the debt. I have been receiving up to 15 calls PER DAY from NRB to the point where i have told them to Black list me. I will not pay NRB a cent, this has been ongoing since 2022? Bunch of ****s that have a God Complex. the operaters have absolutely no idea what prescribed debt means where I have JOHANNA tell me this morning taht my "DEBT " with NRB cannot be seen as [rescribed as I have ACKNOWLEDGED the debt by answering my phone?
