Bad service

I was so inconvenienced by old mutual which left me stranded, when they took my last money on the date which we did not agree on. The money which I had saved from my savings account and transferred to use immediately however it was taken by old mutual. The agreement with the policy is for the debt to go off on the 1st of each month so I don't understand where or what changed. The lady named Nozipho Mkhize which works in the pinetown brunch showed no mercy whatsoever, this situation which I'm in has invonced me so much and their system which they logged for me will only reflect the money in about 48 hours which would not benefit me. I'm at the brunch looking like an idiot being sent from 1 counter to the other and that way I'm seeing lack of service. The agent in Sandile Zondo isn't willing help me as well so my question is what do I do right now as the rest of the staff is leaving because the brunch closed at 5
