Withholding of a device

Last year 9th of April, I had taken my DJI drone I had purchased from the aforementioned store for fixing. Paid R200 for them to take it to what they said is “Physiology”, and then a further R670 for diagnostic. I requested for it to not be fixed as I was quoted R10K for it. I went for an in-store update after 2 months of having taken it there and I was told that they’re tracking the fixing company as it closed down. Every time I go in for an update (the latest was last month), I’m told that I’ll be called back, and I don’t receive any calls or direct updates. It’s been over a year and 2 months now.
