No communication and over charged.

I was double debited by matrix without formal communication being sent to me. I have sent multiple emails and tried to use the watsapp service with no success. I received an email after the fact stating that they’ve changed their debit order process. I want to cancel my services with matrix and I want my money back. This type of service is disgusting, being debited without my consent and then being ignored when I need to query it. It’s two weeks later and I’m not even sure using this platform will work because of the other similar reviews about this company.
