Bad Service from ONAIRTV OA

Hellopeter kindly assist me with OnAirTv I have received my explora in November 21 since then I have not been assisted. The installer has made over 4 bookings since Nov until Dec but they never pitch to connect the decoder and they never communicate anything. Today I am another call to the on air call center I spoke to Ntombi Dlamini who is a customer care agent there when I was about to give her the reference number she says she's offline and I must call back but anyway I explain the query anyway she still insists that she can't help I asked to be transferred to the manager she also cannot assist with that. What is frustrating is that they don't want to follow up on and you must always be the one following up on them they don't bother to call. The ask is here can they please fix this issue it's been open for too long or they collect the decoder
