No answer by remittance department

Good day.<br> I have been trying to reach the remittance department for about a week now. All my calls have gone unanswered . For the second time in two years Jet has handed my account over for collection when I have made regular payments. I would really appreciate a call from this department so that he matter can be attended too. Unfortunately I cannot make to a branch as I work to far from the closest store. I have attempted to clear up the matter with the collections agency and Call Centre but have been referred to this department.
