Double Debiting and Debiting early

Liberty debited our business's Provident amount of over R60 000 on 30 July when for the last 20+ years it has been debited on the 5th of the month. To add insult to injury, I had specifically requested Liberty by e mail on 10 July 2015, to continue debiting on the 5th of the month. Liberty apologised but in the light of subsequently also finding our personal bank account double debited for our personal insurance policy, I am feeling disgruntled and concerned at the poor management. If Liberty with all the resources they have at their disposal, make such a mess, what else are they messing up? And it costs them nothing except the bad publicity from those of us who take the trouble to complain, the customer pays all the costs....
