Miway incompetence

We were clients of Miway, we purchased a new vehicle and our installment for insurance sky rocketed, they phoned us and said that we are requested to install tracker in our vehicle, which we did, but our installment never decreased as promised. We had a minor accident and the bumper needed to be replaced. All of a sudden we had to pay an excess of R5000 but we had an excess waiver. I phoned the call center to requested the call recording of our initial acceptance of our Miway policy, as the agent sold us the excess waiver for a higher installment each month to cover unexpected expenses....they could not provide me with the recording? so another lady phones us, a manager, and she tells us that because we are valued customers we would not have to pay the excess, she will authorize it like that, but that we should take note that if in future we claim, we will be liable for the excess, again I asked for the recording, and it is never sent to us. So by the start of 2020 we decided that we would get quotes from other insurance companies for cheaper cover. On the 15th of January 2020 we wrote a cancellation letter to Miway as our 30 day notice period, we received an auto generated email to confirm they received our correspondence. A call center agent phoned us to ask why we are cancelling and that they would work out a better deal. My husband confirmed with the agent if the calls were recorded, he then proceeded by telling the agent he is not interested in any "new quotes" from Miway as we already signed with a new insurance company. He also confirmed that because we gave notice on the 15th of January (my husband gets paid on the 15th of each month) that it would be the last installment because our new insurance will debit from our account on the 15th of February. After all that, Miway still deducted an installment for February!!!, we now have 2 unpaid debit orders (one of which our new insurance) we stay on a farm, so my husband has to drive to town (35km's) to go to the bank to try and reverse this payment, transfer funds from another account (extra banking fees) not to mention the time he lost from his work to sort out this mess. This could all have been prevented if Miway did what they where supposed to do as per our written notice.. I will never refer anyone to miway!!!!
