Device not working and reported numerous times.

Got my tracking device around end of May but few days later on the 26th May it stopped working. I've reported the matter numerous times, phoned and got hung up twice and the third time was told I'll get a call to set up an appointment for a technician to come through. It's now the 8th June 13 days later and debit order went through on the 31st May, still holding my breathe for that call. And please don't send me another message that you will investigate, it's either you remove or a technician finds me by end of tomorrow
