Can someone please help at FNB

For many days I have tried to authorise SARS payment but I always get an error message E190. I called FNB and was told that my call has been escalated to their technical team who will call me. This was on the 3rd of May and I am still waiting for their call. A new payment was reloaded last night to try to resolve the matter, still getting the same errors message. I am not sure why the payment does not reflect under the efiling tab. In any case, I need this payment done by today as SARS delayed payment attracts penalties. Can someone please assist.
