Terrible customer service and ruining people's lives

I regret ever taking loan with Absa if they not debiting extra amounts now my ITC says I'm in arrears of 5months which is ruining my chances of applying for a bond i have been calling and they are taking me from pillar to post, they have refunded my extra installment that they wrongfully debited Lungile told me it will take 2 days for them to update that i'm not in arrears that never happens is a 3rd week now calling Absa their agent they will tell you they don't know, you ask to speak to the team leader they say team leader thy say he is not available, I was advised that Treveshan Govender will call me but nothing happened, clearly i wasn't too good of a customer to be called by him.FIX MY ACCOUNT YOU ARE RUINING MY LIFE.
