Pension fund documents submitted late due to negligence

I'm starting to lose my patience with this kaak organization and won't be bul**** into silence anymore. I'm no longer one of your employees that you drag by the nose. The HR department in Alberton contact center is so pathetic and unprofessional. I resigned with immediate effect in February and all my documents were submitted way before lockdown. And the other time I had to rectify an error on one of the docs the HR lady by the name of Lacordia had misplaced my banking details, which she had to go fetch from the 2nd building (assessment) now that's negligence. How they got there in the 1st place beats me. Fast-forward to the GEPF I only received an sms from them on the 21st of May that they received my documents from Sars. What nonsense is that, and why were my documents received so late? I sent Lacordia an email wanting to know the exact date my documents were submitted and she gave me a lousy excuse that HR is working from home and most paper work is in the office. So does this mean that if they are working from home no one goes to the office? And they can't make calls to check when my documents were sent. The same contact center that was able to call one of their contact center employees recently to come to the office who didn't make it back home and ended up in hospital. I don't want excuses, I need answers and my money.
