Poor Customer Service

I have signed for a WIFI data deal contract with Telkom in June 2015 with William Ratladi a sales representative with employee number RP100718 who assured me that I would be contacted to get all my details and have my debit order loaded. This has never happened, I decided to go in and enquire personally. I spoke to a gentleman at the Cresta Centre named Billy on the 6th of September who loaded my debit order and accepted payment for the account, he promised to sort the Explora issue out and provide me with feedback within that week. Needless to say feedback was not provided, slightly annoyed I went back into the store on the 13th of September and waited to speak to Billy who then apologised for not providing feedback and requested I leave the issue with him for resolution and not to escalate. The WIFI has been installed back in July, however I have not received my explore as yet. After trying to call Telkom and get through to their absolutely useless call centre, who never seem to answer their calls, I find this is my last resort to have some attention given to my enquiry.
