Credit card dispute. ID number *** LSingh

I am very disappointed with the service that I am getting from the credit card division. I have funds lying as pending and need the money to be reversed back to my credit card. I was told to complete a dispute form. I emailed the form on the 19th of July 2021 and to date my money is still lying under pending as I did not make the purchase, at the time. I have phoned and no one seems to assist. An agent called me yesterday and put me on hold for 45 minutes until it was almost 4pm and I cut the call off. I need my money to purchase but cannot access it as it is still lying as pending. Totally disappointed. Been banking with FNB for almost 20 years and I now want to change as their service is not up to standard.
