Worst service agent

I am on the WhatsApp line with a lady named Juliet, I asked her to cancel and reverse the debit order from my account this debit order has never not even once went off my account since I joined it was intentional but they keep calling me and calling even thou they can see I am not interested. Then yesterday I received an sms stating a debit order of R599.20 will go off my account I wake up today my account is on a minis that amount because the debit order went off and I don't have funds in my account so it made my account go into a minus. The Juliet girl instead of assisting me with the query she goes silent I asked excuse me , she the tells me she's In a meeting I dunno how that how that got to do with me when I clearly stated what my query is, she then comes back to me tells me can you reverse the debit order on your side so I can cancel the policy, what type of service or I dunno what to call it is this? Get my details off your system , reverse that damn debit order I don't want to hear it will take 7 days I'm not interested in that and cancel everything of mine in that company.
