Cartrack - Poor

This is a new review after last week's. Cartrack eventually did the re-install on Saturday. Immediately after the technician left I received a "PowerEvent Alert". This is now happening daily. I contacted them in Monday and received the reply below on Monday morning. We are reaching out to inform you that your repair request has been successfully validated by our Maintenance Team. Our Scheduling Department will be in contact with you shortly to arrange a convenient time for your repair. However, if you do not hear from us soon, please contact us directly on ***. Thank you for your cooperation. Warm regards, The Cartrack Team

It is now Tuesday late afternoon. I am still struggling to get them to come and fix whatever is wrong. Maybe I am just unlucky (or impatient) as I just see good reviews on Cartrack, but this is poor service.
