False offering

I engaged with DSTV's sales department who offered a great deal to retain me as a customer. The deal offered me 3 exploras at a monthly premium of R1140 pm. While speaking to the sales agent I made certain on numerous occassions that I would receive 3 exploras and she confirmed that I would. Today the installers arrived and advised that DSTV had provided them with a job lot for the installation of only 1 explora. I then called their call centre who advised that according to the notes on the system the deal was for 1 decoder only. I have dual view and currently have 2 exploras, why would I opt to only replace 1 decoder? A company who is losing customers at an exponential rate should get the basics right. The premium package is already overpriced and unaffordable considering other options available in the market. I thought that I would bite the bullet and continue with them and opt for the 2 year deal considering that I would receive 3 exploras, but then they disappoint as usual. Well done DSTV you now have a customer who has been with you for over 20 years wanting to cancel his premium subscription.
