FNB is the worst

I recently replaced my card and l was trying to link and manage my account on the website as well as on my phone l noticed that l was struggling to link the new card and decided to call FNB contact center whom l know its a nightmare because of the way they handle the call first l had to hold for close to 30 mins only get through to guy who just transferred my call with out saying a word the next agent l go through to a lady for online assistance and she advice that l have to get my lost cc dissociated with my profile as it was preventing me from logging in and l was given *** which l called and got through to the worst agent ever she was rude to me and advice me l was wasting her time because she didnt have the time to assist me as l was trying to get her name all l remember was that l was back on the queue again this is such shocking service am very disappointed and am sure Post bank can have a better customer service compared to such unhelpful agents l spoke to
