Poor client service and unprofessionalism

I received bad service from an agent by the name Buyisile Maluleke. Firstly the company itself hasn't been professional. I have an account that needs to be debited on 26th but from November 2018 they debited on the last day of the month as well as on my normal pay date. I was informed that I need to go to my bank n reverse that 1 amount, I have to incure the charges for that. The same thing happened in December and January. I called trying to get the issue sorted out and I was advised that from February everything would be in order. In February they did not debit on my normal pay date and when I called I was informed that they would debit on the last day of the month again. I informed the agent who assisted me that they need to change the debit date to my normal pay date and they advised me that from March everything would be in order. On the first of March when I checked my account the debit did not go through and when I called I was informed that I would need to make a manual payment n the company's banking details were sent to me to make a transfer. I did the transfer but on the 2nd of March I realized that they debited my account even after I made a transfer. I requested a refund and was informed that I would get the funds into my account by Wednesday 06/03. After all that I still had to keep calling for follow ups and I had to receive a phone call from my other providers stating that they didn't receive funds in my account and now I'm in arrears due to someone's in competencies and unprofessionalism. When I called to speak to the team leader I'm informed that there is nothing they can do....,will car track burry my family members should something happen to them God forbid coz now my policies also did not receive funds........
