Wack service

This guys had problems with fnb our payments couldn’t reflect on their system we had to send proof of payments which took 2/3 days to get response we even had to pay using different bank, service was restored but catch up forward/rewind services were not restored because of technical error. I waited another 2 days I called they said only the manager would resolve the problem but they are busy now in a meeting and they will attend to it. Today it’s towards month end, I made payments to services I never got mind you I paid twice this month the manager still can’t resolve they still in a meeting. Who should help us?
