Worst company ever.

I found my self paying for two devices on one vehicle, because I was advised to upgrade my device by insurance company. I used the same company for update which is Netstar, they then billed me for two devices, I queried this, but I never received a response, I stopped paying to get their attention, instead of handling my query they handed me over to Nimble. Now I find my self having to pay a huge balance with Nimble. Worst company ever.
