Beyond frustrated with poor customer service for almost 3 months

I sent communique to FNB on 14 October 2021 regarding a dispute of an amount debited from my Credit Card made on 27 Sept 2021. I made numerous follows ups for over a month with Credit Card division, Premier Banking and Credit Card disputes with nil response from either unit and when I called I was passed from pillar to post with no consultant wanting to actually assist but advising that it is another units responsibility. I eventually made a complaint to customer service which is just as useless as the Credit Card and Premier banking division as I have been emailing them for almost 3 weeks now with not even 1 response to my query since their 1st contact with me on 22 November where I was given only a reference number , until today my query has not been resolved almost 3 months later. Your customer service is beyond poor, all consultants do is pass you onto somebody else, you hear kids and unprofessional noises in the background, you can basically hear they are working from home and its as if they are forced to assist you and cant wait to get you off the phone so its easier to pass you onto another unit instead of try to assist I am made to feel like I am dealing with a municipality/government because of how pathetic and frustrating FNB customer service has become.
