Suicidal customer

What in the hell is happening at this company? In November, December an insurance premier was imposed on my profile, because “I failed to prove my insurance” this after I sent it through and I received confirmation that it was received and vetted. On the 20th of this month my debit order went off. Lodged a complaint, the agent advised that I was added to the “early debit order list”. I did not authorize this. I wanted the name of the person who put my name on said list and to date no info was received and call was closed. Yesterday I receive an sms stating my debit is due and it’s a reminder. So I lodged a complaint again. The agent dealing with the complaint advised that there’s a campaign for early debit order and I saw sent an sms. I looked through my phone and I have no such sms. I then advised that my pay date has changed from 26 of the month to last day and wish to change my debit order. Agent advised that my installment will change. Because I will be charged interest from the 26th to 30 or 31st. I am so mad, the amount of stress this place has put me through over the last 3 months. I even started chewing my nails as a result. I even wish to end my life as a result.
