Terrible Customer Service

I have been an FNB Premier customer for 2.5 years. The service levels has gradually decreased to the point where i would like to close out my accounts and move. I sent a request to find out the process of paying off a smart device specifically for this reason and ironically have not received a response to this question nearly 1 and a half weeks later despite the '1 business day' line that is promised.<br> <br> The is not the first time i have had problems receiving responses to my emails and only further confirms that this is not adequate service. Please respond so that i close out my accounts pay for a service which is actually rendered at another bank. Thanks
