FNB's service is disgusting

I recently open an FNB private banking account in April with hopes that I would move over from my current bank to FNB as soon as I received the card I was charged a R150 replacement card fee which was invalid because this was a new card and not a replacement then I sent an email to my allocated banker to assist with this two weeks later that's when I received the call to which I requested that they close the account which is still not done to date then I was charged the service fees on an account that was supposed to be closed long ago. I called on the 29th of April to resolve this issue to date that was not done its now the 11th of May the account is still not closed fees are not reversed and this will eventually have a negative impact on my credit profile the lady I spoke to this morning placed me on hold for 10 minutes when I asked to speak to someone senior to get this issue resolved then eventually my airtime ran out she then made my phone ring once so it actually looks like she called back I didn't answer I am extremely upset because this is a small issue that can be resolved by a click of a button but I must waste my time and money to get this resolved
