No need to be so inconsiderate!!!

I changed bank details and asked Miway to debit the new account. So in error they debited twice...fair enough everyone makes mistakes no harm done so an agent from the call centre asked me to reverse the one debit order as it will take longer to do so on their side...no problem at all its done. However my premium didn't go off in May and I received no notification of this at all. So today I just randomly called in to check if everything is okay and speak to an agent KHULU NGEMA who is so inconsiderate. I kept telling her that the debit order was duplicated so I was asked by a Miway agent to reverse the one and she kept evading that fact and then I finally said to her please check your system and go back to your voice recordings and she still continued avoiding the voice records.After much persistence she still doesn't check but asks me the dates on which the debit orders were duplicated. After being on the phone for 20 minutes she doesn't help much all she ends up saying is you don't have cover and we can only take a premium on the 26th May and you will have to take your car for inspection. I have asked her to get her manager to call me back...Now begins the wait!!!
