FNB Service failure

For a bank that has the highest charges, I'm extremely disappointed that all those charges are for nothing.

I queried why I am unable to transact between my credit card and my main account. Some consultant advised after I went through 5 agents that it's because the credit card has expired and there will be a delivery of a new card, at this point I had missed the appoint with some q Courier people after I told them to take it to the branch. I followed up with the branch, which was useless cs they give you a phone to call a call centre of the credit card department. I held on at the branch phone until the line just cut me. This is my time and resources but because I'm unable to transact and it affects me, I try again. I called the credit card department again, they bluntly said they don't know how to help me. I tried again yesterday to contact thecourier after FNB said I should reach out to them. The courier sent meback to fnb and said fnb needs to order the card again. I'm so frustrated by then and asked them to call me. Theu called an hour later. Because it was almost knock off time, agent calls me and keeps quiet. Iknow this stunt cs I've been in the industry for years myself. She reached me again today, when we wrre supposed to do a security check, she pulled the stunt again and told me that there's something wrong with her system, I held for her, she returned to the call and acted like she can't hear me...that time the line is very clear. FNB is supposed to be top class according to how much we pay them but their customer serviceis pathetic. I must just cancel my business account with them as well as my main account. Agent didn't even attempt to call me back. I must follow them around to assist me.
