Bad service

I have been banking with fnb since the beginning of time. About 4 weeks ago, I got a offer to upgrade my accounts with them ( both debit and credit) which I took. I did everything over the phone and everything was good. I set up the delivery of both cards to the cresta branch. The week of the 14th I received a message from them stating that my cards are ready for collection. When I got to the bank, only 1 card was available. ( debit). I asked for the status of my credit and I was told I did not sign the forms, meaning I should just restart the process. Which I did and resigned the credit form. On the 16th,I received a message stating my card is ready and should collect it at the cresta branch. When I go to the branch that Saturday, my card is still not there and my status is still incomplete. I resign the forms at the bank and re order a new card ( again). I receive a message again the week of the 25th stating my card is ready. When I get to the bank again on the 26th, my credit card has the wrong name on it, and still the increase is not reflecting in my account. I had asked one of the officers at the bank and I am told I should wait 7-10 days for processing. On the 29th of March, After waiting 3 weeks, I contact the bank again. Again I am told my forms are not signed and I should resign. I resign the forms for the 100th time and try send them via secure chat but by the time I tried, the officer already left the chat before I could even send them. I sent them via email. When I try to contact the credit card desk via the secure chat again, I was told I am number 41 in the queue. I waited 3 hours and no one came to my assistance. It’s is now the 30th of March and still no word from fnb. This is very unprofessional and because of this, I am seriously thinking of switching banks. Debit orders are about to bounce because of this unprofessional Behaviour from you guys which I don’t appreciate.
