Atrocious service

Month of March their staff made me for the March premium because the didn't go through. They then debited my account a few later. When I told them I paid twice they asked for proof of payment which I sent by e-mail to a lady called Staph. She confirmed receipt but never did anything to allocate the funds. Later I call again and spoke to Brent, the same conversation was had and still nothing but all they do is call me to remind me I have not paid for April. The last person I spike to is Olwethu who also now is not responding to my e-mails.
