Bad service

Pathetic service ever.i have called since from last month to ask them to go to proline to diinstall the dervice,I gave them the address the person who was in charge,yesterday I called them again Robin said she will send a technician to install the device into my new device.the technician arrived today but he was told not to install any device,I spoke with Robin again and she said I must do a fellow up she was sòo rude including the manager he even told me I'm more than welcome to cancel my contract.
