Poor service

And here we are again I was told that the technician will be here at 09h00 on 2022/12/30 to fit the new tracker unit and he phoned me at 14h40 to say he had a cancelation and can he come now, and I told him that I made it clear to the call centre I will only be home untill 11h00. So thank you Netstar to show me once again that you do not know how to run your company.
