********** debits- No system Installed.

I recently app**** for a security system to be installed in my home in March just before lockdown. But due to a family member being quarantined we didn’t allow any visitors in and told them they would send someone to install when it was safe to do so, therefore hold my application. April 25 National security debited my account for R859 . I called them and spoke to manager in Durban branch named Val and she said she would investigate. I therefore sent an email to her on 13 May asking that she stop the debit and refund me . She told me she did investigate and I would be refunded via email. I continued asking when the refund would be through via email and no response was given. On 25 May another debit of R379 went off . I called and emailed Val. She told me she had processed the credit and that her senior Nolen and another I think named Glancy had not signed it although she had processed it and that I should be aware that in June I would be debited again since billing has gone through. How is this possible. WHAT KIND OF ***** IS NATIONAL SECURITY DOING ???? Debiting my account without any installation done. Shoving the blame to eachother, and why do I even need to know this because I want my refunds and this to stop. To my dismay I can’t even reverse the debits as the bank FNB is unable to do reversals at this stage due to their lockdown system. NATIONAL SECURITY I WANT MY MONEY BACK AND I DONT EVEN WANT THE INSTALLATION ANYMORE. I’m so frustrated and disappointed . I want this to be sorted out IMMEDIATELY AND NOT WAIT FOR JUNE DEBIT TO GO OFF.
