Complete incompetence & zero follow up

On 16th December I entered into a contract with Telkom to provide an internet package comprising 50Gigs data at 10Mbps. On 12th January equipment was delivered by a courier. Part of the package included a Multichoice Explorer decoder, I am still waiting for that, the helpline say it's nothing to do with them and the Telkom shop don't have any information regarding decoders either. The package also came with 2 x data cards and 2 x phone cards, none of these cards have been enabled despite 5 visits to my local Telkom store at Canal Walk Century City. I was even given another set of 4 x cards, for whatever reason but these are still in the packaging as I have no instruction regarding what to do with them. I have paid R10 parking each time I have visited the store, but receive no feedback at all. I have threatened to cancel my contract due to non supply of part of the equipment and or service, but just no-one gets back to me regarding my problem or my threat. I have a recent Telkom reference number 424CWK 19/12/14 and am totally exasperated.
