Lots of Calls from African bank in one day

I have complain about African Bank ,1. their numbers listed online are incorrect , 2. They are harassing me all the time in one day I receive more than 5 calls they call me early hours of the morning before 8am , they call me after 9pm , call me throughout the day is it even legal that kind of harassment.<br> <br> Firstly I just wanted to say that I'm not in any arrears at all , Infact I have paid in advance for 3 months because of the financial difficulty that I am experiencing right now , I even told they consultant that I'm financial difficulty & that I will pay for 3 months in advance & because I knew month end I won't be abled but instead , they call me everyday & I keep telling them the same thing , their lack of professionalism is massive issue. African bank Please Stop call me at least 5 times per day & update your systems & put the correct numbers online so that your consumers can be abled to get in touch with you guys
