After paying for 3 months still no DsTV Explora

On 30 June 2015 my partner, Kim B MacLennan, and I took out a 24 month contract for adsl with Telkom, a deal that included a new router and the DsTV Explora decoder. Telkom stated that there was no stock of the decoder but that when stock came in they would deliver the items. After numerous calls, including reference numbers and escalations, visits to Blue Route Telkom (very rude), we are no closer to a resolution. Meanwhile we are paying for the increase in data and have even been double billed for one month (old plan and new plan billed). The call centre told us to go to the branch and the branches (Blue Route and Claremont) have been unable to help. There is simply nowhere else to turn! The call centre has made promises that they have not kept, they never call back when they promise and they are failing to uphold their side of the contract. This is unacceptable and *********.
