Can't Access the Web on Wireless Broadband

I subscribed to Telkom's wireless broadband. The equipment that is router and sim card was delivered on 9th October 2015. Despite this I couldn't access the internet so phoned in and was told that sim card needed to be activated. This was done on the 12th of October 2015. However still couldn't access the internet and was told that internet access wasn't activated on the sim and I need to wait at 72 hours for this to be resolved. I phoned in today and was told that it would take at least 21 days before this could be resolved. I am a new Telkom client and this is not the kind of service that I would expect. Very Disappointed. I am thinking of cancelling the contract due to poor services.
