Netstar doesn’t want to refund me

I took out a tracking device with Netstar which was prepaid in December 2019, June 2020 I bought I new vehicle and requested Netstar to remove the tracking device from the old vehicle to the new since it was prepaid but however they kept sending me from pillar to post. I ended up canceling with them and getting a device with another company. At first I was informed that I will receive my refund for the prepaid device within 14 working days, after those working days when I called to check how far the process is, I was informed by Their agent that they don’t know who is supposed to process the refund. After a few days of calling and not getting a straight answer I demanded to speak to their manager. At first I was transferred to the supervisor of the credits department Nokuthula Mchunu who informed me that the matter will be escalated to the manager as soon as she is available. She then later called and informed me that she will be contacting the dealership where I had purchased my car to check if it is indeed settled, and about a week later she called and said that they have made a refund to the dealership since I purchased the device through them and they will refund me, fine I asked them to send me details of the person who is in charge of the matter at the dealership so I can directly contact them and they said they will, to date I’m still waiting for that email. Ok, a week ago I contacted the dealership to check on the matter only to find that they have no ideas of such a refund. The dealership even took a step to send them an email requesting them to contact me and I also sent them an email with the people from the dealership included to find out what is happening but to date there have not responded. I’ve been going up and down with this matter for over two months now! Netstar is trash!
