Bad Service! **********!!!!!!!!!!!!

I have had my policy since 1 March 2018, I received a call in August to inform me that payment was not received for April 2018. An hour later i got another call to say that my payment was found and that there was nothing to worry about. However, at the end of August, my account was double debited, when I called in, the consultant advised that they are processing my refund and it would be paid into my account by 13/09/2018. I called back today (14/09/2018) and got told that my refund was denied. I would like to understand how this company does anything when they can't even keep track of the payments. Since i signed up with them, I have had nothing but bad service!!! I would like a full refund of every cent I've paid to them, as has been requested numerous times as I refuse to deal with this terrible service, especially since I have never used the services at all.
