Bank account hackers!

Im disgusted. I agreed to a quote then said I would join end of June as I am still with Outsurance until then, you agreed to that. Then you went ahead and sent an immediate debicheck mandate which I ignored then somehow anyway debited my account this morning without my permission! I was with you for years previously and this is how you treat potential clients? You bunch of *******! I am horrified at your behavior! Is it going so bad with you that you ***** from South Africans now? You will never ever see me again as a client and I will tell anyone who will listen what you do to people! I will climb all over social media and testify to what you have done to me today you greedy little ****s! I have reversed this and put a stop and I will continue to do so. I will also take this up with the Ombudsman. You skelems! My bank cant even explain properly how you bypassed their security protocols!
