RCS :Store Account Replacement

I have been trying to get my Pick n Pay Store account card replaced since November to date, I have called into the Call center several times with no response, I have emailed them countless times still no response, I have visited PnP stores and still haven't received any useful assistance, even tried sending a Whatsapp message the outcome is still the same. I am currently in arrears because I am unable to pay for my account without my store account details being loaded on my new smart shopper card.
