Miway employees need to wake up

I cancelled my insurance with Miway as I wasnt happy with the service which led to me finding a better deal with another insurer. Now this is where I'd like to add in that i'm not happy with ABSA's internet banking capabilities. After Miway processed the debit order for March on the 23rd of February(the agreed debit order date is the 1st) I was not able to reverse it on my internet banking!? As it was not even listed with the other debit orders, but surely my account was debited. I did however manage to stop payment for future debit orders as I cancelled my insurance with Miway. Fast forward to today, the 23rd of March, low and behold Miway processed another debit order!!?? For a different premium amount; the offer they made when i notified them of my cancellation - which I REJECTED. And once again ABSA adds to my irritation(to put it mildly) , with no trace of the debit order among the list which can be reversed, how will i get my money back?? -this would now be the second month for which Ive paid a double insurance premium. Now I have to spend my valuable time sorting out incopetent service providers' messes! Absolutely unacceptable
