Vodacom Blue Route Mall

I have had the worst encounter with Vodacom Blue Route mall. I had a contract with them, my phone was booked in for repairs in July 2020. When I went to check for the phone, they told me it was beyond repairs but they can't seem to locate it. I have been paying for a phone that I don't have since last year, because of their negligence. I need assistance with them because when I contact the manager for the past 3 months, he says he will call me back and never does. I really don't rate the store at all.
