Late delivery and no installer available

I recently went with the DSTV explora deal of R119 per month including installation and purchsed the deal for telephonically on Saturday 18 November 2017. I was told by Sharon the delivery would take 2 to 3 days. It is now 29 November 2017 and only receieved my decoder today. Furthermore, I stay in Bellville and none of the installers in my area do installations affiliated to your company. I contacted you service centre again and was told I need to wait another 36 hours to be be contacted by installer. Onair tv you are not honoring your side of the contract. I only went with this deal because of what was promised by your sales lady. I am seriosly considering canceling are rather going with an installer directly as I did in the past. This process has proved to be more of an inconvenience than anything else and after 11 days of waiting I now cant find an installer in my area and I am expected to wait another 3 days before I can have my installation done.

Can you please assist as soon as possible?

Thank you
