Money taken even though I told them I was not interested in cover with them!

I requested a quote from budget insurance and my current insurer matched the quote and I spoke to two consultants and sent an email to budget insurance that I was not interested in their cover and today they took R899 from my account. Now they are saying there was no communication on their side to say I was not interested and I have to wait 7to10 working days for my money back and that means my other debit orders will fall short. There was no. Debicheck authorization done on my banking app and they refuse to accept that any communication was sent from my side. I spoke with debby Prokopos now and I have to wait for MY MONEY is all I was advised.
