FNB Poor service

I made a call to the FNB call center as I had a issue with increasing my daily limit for payments. I do have online banking and the FNB app. my device was not linking to the app so I thought it would be best to call to have my limit changed. my first person to assist me said he cannot assist me I must go through to online banking department. I then get to online banking after waiting almost another 20min in call queue. this agent asks my ID number and in a few seconds after that im told u at the wrong department , and he sends me to delivery of a device department. this is the worst experience I have ever had and I think it will be best to cancel my account with FNB as if this is the type of service I receive then I don't see myself as a valued customer. I work in the call center industry and if my agents spoke to my customer and did what they did which is deemed as call avoidance not willing to assist, not sure if you train them well enough to deal with customers but it is pathetic service. I feel like I need to let everyone know what FNB does with there customers cause clearly I must spend my time being transferred to different departments all day for a simply change.
