Cancelled Routers VOX

I have 2 cancellations on my VOX customer portal. The one has been cancelled JUNE 2024 and the other one DEC 2024, I was contacted by SKYNET and numerous times i have asked them via channels to please call me on my LANDLINE as Im not allowed to take private calls during working hours to NO avail... I have arranged pick up for the router at my house as the kids had holidays in Dec and was home they never picked up the router. Now im being invoiced R1999 rand for a router that has not been returned and getting suspension warnings. Funny thing about this all is that i have TWO routers that belong to VOX... One router has been cancelled JUNE 2024 and till this day have not been invoiced or anyone contacted me to return the router MICROTIK as they call it. I have both these routers now at my work, and i have contacted VOX to come and pick these routers up and all they can say is that SKYNET has contacted me twice and that i now need to return these routers to the head office in CENTURION, im from Boksburg, BAD SERIVE BAD CLIENT SERVICE and very disappointing as i have been a client for so long i just feel that i need to get treated a bit better????
