No accountability at FNB

Good morning So, I used the Fnb online banking platform to open a cheque account and a credit card account. The credit card application was rejected, only the cheque account is activated. On Monday, April the 8th, I mistakenly transferred money from my Paypal account into my 'credit card account'.( The account that doesn't exist, or is inactive) Two weeks later, I am nowhere near getting the money taken out of the non-existent credit account to my cheque account. I am told to write emails to certain people and get promised turnaround times, after which my query gets redirected to a different person, who comes with a different turnaround time!!!! When I ask to speak to someone to complain, I get told I must put it on email, I can't speak to anyone!!! The lack of empathy and disregard for my situation by this bank is astounding to say the least, they have my money in their system and they are telling me to wait until they are ready to give it back to me!!!!
