FNB Private Clients call centre giving me the worst service ever

I called FNB Private Banking on Wednesday 23 September 2020 requesting a letter that confirms that I have closed my account. I also requested them to confirm my credit card limit on the same letter. They said their turnaround time is 48 hours.

Today I have called FNB private clients call centre over three time requesting the letter. The last lady I spoke to made me hold for 30 minutes (14h30 - 15h00) and she said she was checking my profile.

FNB can you please issue me with the letter and clear my credit record that gives false information hence I am requesting this letter.

Regards Unhappy client
