Pathetic service

The worst service i got from any service provider in my life!!! My tracker unit was not active from the 28th of November last year,after e mails and telephone calls and appointments that get moved without my concern i still don't get any joy. For more than a month i am exposed with no cover from tracker,the least to say pathetic. They get there money every month,that is where it stop from them,be warned. Don't call them on a saterday,only ground level staff on duty, being holding on the phone for more than a hour,they can not get a senior person to talk to me!!!
