debit orders to a closed account

I am extremely furious with how clientele does not take client request serious<br> <br> On the 03 June I had requested that the company should change my banking details, and they failed to do so. they debited the premium on the old account which I got bank charges of R 153 from standard bank for a failed debit order. they apologised for the unnecessary cost however they did not compensate me for those charges. I had to make the premium payment myself, now on the 11 July they continue to do the same thing, I do not know how many times I should give clientele the same request. Because I refuse to incur these unnecessarily bank charges, for simple instruction that I had given to their company. I want to be compensated for those charges and I want the company to do a proper job. Also the debit order is supposed to go off from my new account on 15th of every month. Not earlier than that, especially when the 15th is during the week this does not justify the debit you made to my old account. <br> <br> I am tired of these endless charges they are making me incur for their lack incompetence. On the 09 June I had specifically requested that they do not make any further attempts for the debit.
