Failure to replace debit card

I went to your Karaglen branch yesterday to replace my debit card and I was not assisted . Even today still don't have the card . 🙃. I was told that before I can replace the card I should accept a debit mandate for my old credit card that was in arrears , I hardly understood this instructions to say what are you debiting from an account without income as it's going to bounce and cause me bank fees.I tried to explain that I'm unemployed for a whole number of months I'm even struggling to survive myself, and explained I will deal with card once I have stable income . Out of frustrations I eventually agreed to accept the mandate on the FNB account that the consultant requested me to, I tried my fnb app, dial string , ATM and even went to FNB there was no mandate . I went back to capitec I was told FNB rejected the mandate , went back to FNB they said nothing shows on their side . So capitec let's make simple if you not going to replace my card just close the account and give me my cents that are in the account. Contact me on ***.
