No DSL delivery

At the start of August I placed an order for a Telkom landline. This was completed and I then placed an order for a ADSL line on 20 August. I specifically queried the capacity at the exchange at the time as I am in a remote area and was assured there was no problem, following which I payed for and placed an order. I was informed at the time that the turn around time is 7 to 10 working days. I was not contacted and made follow up in the first week of September to be informed that it could take 21 days. So I waited and after numerous phone calls and being transferred around at the call centre I was informed on the 1st of October that the installation was scheduled for 13 Oct. Having not received any confirmation I followed up again today to be told that my order will now take 12 months to complete as there is no infrastructure. Leaving me extremely frustrated as this is what I asked for out the outset and payed for the installation in good faith with the understanding that it would be completed in 10 days. Had I known this at the start I would never have payed for a service that I may only receive in a year
