3rd complaint and still not resolved!

this is my 3rd complaint on 3 different cases, its sad that FNB has deteriorated into such terrible service, this complaint refers to an account that was paid up in 2018, upon my homeloans applications they FNB could not proceed and they FNB needed confirmation that my account which is with FNB be closed. ridiculous i know.. got a very unhelpful person to "assist" only to take 4 days to tell me that i need to close the account.. i call.. this Darren person refused to provide his surname and now i can understand why because this was bound to end up on Hello Peter.. provided me with a reference number to say that they will close the account and this will take 2 - 3 working days.. fine... i wait.. 4th working day no feedback.. i call and hold on for 7 minutes and no one answers so i drop.. called on the 5th working day for feedback as this stupid admin process is holding up my home loan and again no answer for several minutes... Sick and tired of such pathetic service! Up until now my 2nd complaint is not resolved when the agent placed my on mute till now 3rd week later.. no feedback.. i doubt id get this matter resolved either but instead of speaking to *********** people i rather let the public know how fantastically a customer of over 20 years is being treated
