OnAirTV only promises - no service

Took out deal on 1 Aug 2017 with promise of one week to install. No feedback - I had to follow-up. R99 deal for explora1 and 2 installation incl. Deliver 23 Aug. Had to phone for installers (Matanyeni). Make appointment on 9 Sept. Pitch 2 and half hours late. Install and pairing did not work. Indicate I must wait 1 hour. No view. Arrange for 17h00 same day - did not pitch. Then for Sunday - 08h30 - did not pitch. No apologies - I had to follow up. Appointment set for Monday - not pitched and same on Tuesday. Wanted to cancel but OnAirTV say cannot after installation.
