I'll try to be brief because this issue has been going on for 6 yrs now with this company.
We purchased and fully paid for a unit that we could attach to a video camera in the field and transmit the audio and video back to our control room for live shots using 3g or Wi-Fi. Needless to say the unit has never worked properly. The company has come down to our office numerous times throughout the 6 yrs to try and monkey with it. They've also said numerous times that they "totally re-designed" the unit and that it's working.
So fast forward to today. We have not heard back from this company since the last failed attempt when they were at our office back in May of 2017. To make matters worse, they have the unit and we gave them a video camera to test it with, so we paid about $16K for a unit we do not have in our possession and they have a video camera of ours as well. In the meantime, several of their staff have resigned leaving just the owner to deal with.
I've sent letters to the Better Business Bureau and Attorney General's Office of Consumer Affairs but they have stated they can't help us because the warranty on the unit has expired (which is frustrating because we only had the unit in our possession to use for about 2 months, so how can a warranty be applied?)
So that's the short version of this 6 yrs. + nightmare.
If you need any type of proof I have all the email exchanges and the invoice for the units.
