FNB Not Providing Statements Is Suspicious

I'm very annoyed at the incompetence of FNB staff. I noticed that my account statements for October 2020 and December 2020 were missing. I contacted the FNB chat who advised they cannot assist me I must go to my nearest branch. I see no need to travel to my nearest branch the error lies with FNB. I then called customer care who acknowledged the absence of the statements but could not give an explanation. They said they would forward the complaint to the technical department and it would be rectified. However, the error is on going nothing rectified. My March 2021 statement is missing. How is one supposed to download statements if they do not exist and FNB is clearly not interested in resolving the issue?
