Constant Harrassment

During 2007/2008 I had two loans with African Bank and had to undergo a payment arrangement. I am now constantly hounded by the Call Centre, 3 to 5 times a week, emails sent to my account at 00:00 at night, calls now even made to me during working hours, or Saturdays and Sundays as early as 07:45.<br> <br> I made an arrangement in 2012 or 2013, which I have not deviated from, yet I am being pressured into a new arrangement that I cannot afford by constant harassment, in the hopes that I will give in.<br> <br> I have emailed African Bank regarding the complaint, which has just caused the constant phoning to increase. So far, I've been called 5 times today.<br> <br> All I want, is an email confirming that they accept my affordable arrangement, as they cannot be trusted to telephonically commit.<br>
