Worst customer service via the APP

Worst online customer service experience. Tried via the SecureChat on the app which was the most frustrating experience ever - slow response time and they didn't respond correctly to the issue I put to them. I eventually got to speak to a consultant on my mobile which wasn't any better as he was not listening to what I was explaining to him. I was having problems with changing my daily limits as apparently my online banking login was verified, however I had had this sorted out the previous week. He couldn't tell me why it wasn't verifying. I logged a call with their complaint department and then decided to try to change my limits again online - someone had obviously rectified the error on their side. FNB's securechat on the app has got to be the worst customer service ever. Will not use that route again to resolve any issues.
