BAD BAD SERVICE

Since i send my refund request to FNB since last month i never receive any feedback. I had to complain on their webside or call them to ask to speak to manager that is when i will get helped. Since i reeeived their e-mail on 09.06.2020 till today no one ever came back to me. what happened is that i put an incorrect account no when i was paying my Dept account then i spoke to their consultant they said i ahve to send proof of that payment and bank statement to confirm that that money went through which is did. I never experience such a Pathetic service as speacially being with you guys(FNB) for over 15 years.
