Avoiding Me - Has my Repair gone missing??????????

I booked in my HisenseH218 Router on 05 or 06 December 2020 Vodacom 4U Greenstone. 06 December I got my Job Number. I have been phoning up and down, after Greenstone ever since, to get feedback on my repair. All I get told is "Give me your Job Number, we will call you back". The callback NEVER happens. When I call the repairs line, I am told that I need to speak to Greenstone, as my repair was sent back to them. My Repair is listed as cancelled! If I recall correctly from the conversations with the Repairs Line, it is due to Repairs not being able to locate the IMEI or something like that. But only Greenstone has the full information. Yet again, a "we will call you back" that never happens. When I left a message for the in-store Technician, he never phoned me back. When I called again and eventually spoke to him, his response was "And why did I have to call you?" We are now almost 2 months down the line with no answers and a full mailbox when I try contact the store. The poor Repairs Line lady is more concerned that she cannot help me any more than ask me to call again later, because she too, cannot get through! I am starting to wonder if they have lost my device and this is why they are not contacting me??? Needless to say, I am beyond unsatisfied at this point.
