FNB CREDIT CARD HAS *********** STAFF!

I renewed my credit card online end of April as it expires the end of June and since then have been running up and down trying to see where the card is. I have had no response, no answers, have been put through to person to person and told numerous things. This morning I called FNB CC, and was told my new card is with UTI, but UTI says they are still waiting for my card to be sent to them so they can deliver it. I am done running after FNB, after being a client for more than 20 years! How can I trust a bank with my money if they fail at simple tasks like this?! Every time. Every time I have to renew my cards it's a problem!!!! I can't get help online, on app on social media, do I really have to go into the bank again only to be handed the phone and be told to sort it out myself?!
