Revolving Facility- useless private clients

Ive been struggling for months trying to sort out my revolving facility, havent been able to access it , Ive spoken to many advisors which have all been useless, all say it should resolve in a day or 2 and then it doesnt. Whats the ****** point in having a private clients account if they are useless? Even emailing the revolving facility department as they have requested doesnt work because nobody gets back to you at all, I have been with FNB for more than a decade and ive always made payments on time, As soon as my divorce finalises im taking my credit lines elsewhere
