POOR SERVICE

Poor service, I have been enquiring about my unit which is reflecting the incorrect position since Monday. I've been sent from pillar to post by the consultants telling me the unit is perfectly working, I just need to drive my car for 7km as they have rebooted it on their side. Finally today one of your consultants finds the strength and tells me they need to book it for repairs at my cost as the unit stopped working in June(which is a lie). The last positioning is on the 29 July @18:00. I've been a loyal customer for the past 4 years and religiously tested the unit as per instruction. I can safely say you have lost a customer as I will not be held liable for the repair you are talking about.
