Duplicated account debit

To my surprise Liberty debited account twice this month for a single Life Cover having with them. I tried to contact broker. He confirmed that they know what happen. I see that they've done the same thing with my wife retirement policy. It happen to many of their client, it is all over the social media. Now I wonder is this is a new business policy by Liberty, or many SA Corporate businesses. MTN did the same move, *******ly using clients money making own balance sheet looking pretty. Definitely I will revoke my bank account debit order and will look for another life insurance provider. I want give them another chance to dig into my account again. I lost confidence in this crowd. No excuses please..
