External Antenna Installation Damaged Property

The installation team that put up my external antenna for my new LTE uncapped service badly damaged the wall plaster surrounding my external vent and damaged the internal side of the vent itself.<br> <br> My wife was at home at the time of the installation and they left without even mentioning anything. I called the LTE call centre yesterday to lay a complaint (Case Number: ***6) but have heard nothing further.<br> <br> Telkom please send someone to come and re-plaster the damage, re-paint and re-install the internal vent. The wiring is also poorly secured.
