Pathetic Service

I have contacted FNB today via phone and chat. My phone calls are dropped as the agents allegedly cannot hear me. I then used the chat feature, explained the situation and error on FNBs end - got transferred, chat was then dropped. I started the chat again, agent tells me to call in rather. WHAT AM I SUPPOSED to do get help if neither phone or chat works???? This service is pathetic. No one offers to call me back or to escalate the matter. This is one of the reasons why I am switching banks.
