Hi-Fi Corporation *****s money from clients and ignores all calls after not upholding their SLA

The worst service ever. Paid for a washing machine 15 days ago, it wasn't delivered. They marked it as delivered. I am trying to get a refund. Have been daily, multiple times with promises of getting back to me, refund pending etc. They have not called me once, escalations taking place but no feedback. I am now going to SAPS to file a case of theft for my money that is not being returned and I will report them to SARS as well to be investigated. Money is being ******, no help from HiFi Corp, their online team or the Incredible Connection in Fourways where the machine was shipped from. The utter disregard for clients, their money and service is disgusting. Emails not working. Sent to the supervisor ***, the head office email is also not working. Multiple calls with ticket numbers and case number to no avail.
