Paid for a unit and no service

Good day. So I sent an email to renew my contract on Monday the 7 September. The sales person tells me I should install new unit after the 15th September or else they will charge me cancellation fees. The people from the installation calls. I tell them to schedule it for after the 15th because I dont want to be charged cancellation fees. I was put on hold and the gentleman tells me I wont be charged and I can schedule an appointment. He insists on monday 7th September when I told him I'm not sure. So I go into to the app to monitor my vehicles and guess what I find.... The renewed vehicle is MISSING. I sent 11 emails to tracker.... they tried calling once..... Disgusting service. Disgusting attitude. Disgusting treatment. I demand a credit for Services I paid for already and I'm not getting. You a waste of time. I am praying that I find another tracking company worthy of my lousy 5c. You Do NOT value your customers at all. ELEVEN EMAILS IS NOT FUNNY ANYMORE.
