Agent who things is superior

I called in as Old mutual finance has deducted twice on my account and the agent I spoke to had this bad attitude instead of helping me he just told me I wasn’t listening to him I need to listen to him. I was very disappointed in his manner he handled the query as all I was requesting is for him to send an email to his manager to just follow up on my previous logged query not for him to explain what has happened because that isn’t helping me I needs for the incorrect debits to stop.
