Tracker and its shaduy business

Customers, please be very careful about tracker. They are non responsive to customers when we reach out. I promptly informed them about change of ownership on July 30 and with their unprofessionalism, they called and confirmed with me but did not follow up with the new owner thereafter. Now I have left the country and I still keep getting billed. I’ve sent several emails and they never acknowledged. As foolish as they can be, they try to contact me on phone and it’s obvious my cell phone is no more functional, which with any common sense should know that. Now I’m stuck with them paying money for a new owner because of trackers unprofessionalism. Be super careful with this joker behaviour.
