Disappointing and angry

I received an explore 3 decoder on the 13/05/19 of the offer of R499.00, I was called by *****gwa. Few day after a I called multichoice I got Salaminah who was very good in attending my problem. The challenge I am facing is that the installer that was assigned to come and install the decoder came on the 21/05/19 after so any attempts of calling mutlichoice. When BAFANA the installer came he did not do the job he said he didn't have enough cable he will come the following day. The following day on the time we agreed on I called him he said he's not around, he then switched off his phone. I contacted Multichoce agent in Springs I found THABANG , he promised to follow up my problem. He never did, I have been on the phone since they are not picking up the phone. I am disappointed and very angry on the serves I get because I use airtime to make calls which are not of use to me. I strongly feel that multichoice (Springs) is failing me. The option is to collect the decoder as it is not of use to me.
