Horrible experience with BlingStallation

I am extremely disappointed with the service that received from BlingStallation. I hear some praising them but it was horrible dealing with them. I bought a voucher at Makro Silverlakes on 14 November to install an explora decoder. I went for two weeks without any contact from BlingStallation. I followed up with Makro on 28 November and then I got a call and provided details that I could and agreed that they would call back around 3pm for the other details. Then I phoned on 2 December to follow-up. The lady who answered the phone only said she would call back. Nothing happened. Then on 03 December I made a follow-up and was told to wait for scheduling department to send an email with date. During our conversation, I explained to the lady that I only have a decoder what else will be required from my side. She said everything material will be supp**** including 25m cable LNB and satellite dish. She concluded that apart from that, it will be cost of extra labour time and extra length of cable. I only got the date 07 December for 18 Dec 2020. The appointment was cancelled an hour before time due to rain. This was rescheduled to Sunday 20 December at 2pm. The technician arrived and I showed him where installation was supposed to take place. then came the story, I was told, I would need a smart LNB for R550, satellite dish for R600 and additional labour R325. I then said this is not what I was told. He then began signing some notes on his tablet and took pictures of the yellow terms and conditions receipt/voucher. And said we are taking the yellow form and it will be uploaded on your profile. Then we discussed possible alternatives. He asked me to sign on the tablet and he took the yellow receipt without any explanation. Then on 21 Dec 2020, I called BlingStallation about the matter and the options, I was told that the technician came to the place and by that, the voucher was actually redeemed and I have to start the process again. My goodness!!!! Just like that money is gone and the technician never explained whilst I asked him 3 or so times, what it meant that they came and the installation did not take place. What disappointed me is the inconsistent advice I got when I phoned the office then this technician quietly took away the voucher and redeemed it.
