Poor service

Good afternoon,

I trust this message goes straight to head of department, I’m writing in so much disappointment, As I’ve been paying my car tracking devices but it’s not working, I’ve been complaining about this to their head offices nothing has been done about it so they telling me I must keep on paying for something that is not working on my phone no technician have ever been sent to come and assess what is the issue with the tracking devices. Is it fair for me to pay for something that is not working. I’m so disappointed and feel so disrespected by your company please attend to this ASAP I will need a refund of my premiums that I’ve been paying you without getting any service from you guys.
