Paid for a phone I havent received

I app**** online for a phone (Samsung S8) in May 2017. Got the call and was successful with the application. A few days later I get another call to confirm banking details, they need to debit my account for the first month (which they did, R499), will receive phone between 5-10 working days. July I contacted them as i havent received my phone. The lady says my application was unsuccessful. Its 28 November 2017 and still no one has helped or contacted me to reimburse my money. I contact them almost every week on Facebook and they have now started ignoring me and deleting my comments. I am already a customer of Telkom, I Have uncapped for my home. I am SOOOOOOOOO regretful that I ever decided to make use of them. The only time I was almost assisted was when I received an email asking for proof of payment, sent it, and 4 months later, email upon email to them, they ignore me.
