Disgusted with service received

My bank account was debited five times this morning also last month the same happened, when I called in to FNB this morning I was shocked and disgusted with the service I received this morning by FNB collections department. I was told this morning by Ms Mita Tsheola that FNB can debit my account as they feel fit no matter how much times and when, I then told her that according to me I'm in arrears for one month which a arrangement was made with there department for one month she then pointed out to me that they have been trying to make contact with me *** I then informed her that this is not my no and I don't even live in in that region. I checked with my closet FNB branch and all my contact details is correct.<br> I'm currently left with a big dent in my bank balance due to FNB's *********** and unprofessional staff. I've been a loyal FNB client for many years and this is really questioning my future with the bank. <br> THIS A BIG CONCERN FOR ME THAT MY CONTACT DETAILS IS BEING CHANGED WITHOUT MY CONSENT, MY INFORMATION SHOULD BE SAFEGUARDED , AND THAT FNB IS DEDUCTING MY MONEY AS THEY FEEL FIT. <br> <br> Please anybody assist with this matter.
