DSTV Installers

On Internet business name is: DSTV Pretoria, no exact address, only cellphone number but advertise as 24 hrs business. I call them on 25 Nov to repair my new installation of DSTV system. They come to my house 1,5h later than promised but I already have somebody else to do the repair as I thought they are not coming. Eventually the phone that are at my gate but the job was done already what I told the over the phone. They agreed but to recover they call out expenses, they stole my outer intercom unit. (I got it in the camera)Since then, they don't even answer my calls. DSTV approved ******** installers.
