Worse tracking Company ever

Netstar worse service received every. I have both a new car and wanted to cancel the tracking in the old car. Lady with the name of Neo help me on Tuesday and she was supposed to send me the contract and make me listen to the telephone recordings today no one called or send me an email. try to call them today and they say I have reach them within their business hour which is Monday to Friday from 08:00 - 17:00. It is Friday after and it is 14:10 and no one to take my calls. I can not believe this is the people I have trust to look after my car for two years now. I am so disgust by the service received. I will never used Netstar again for refer them.
