Disgusting customer service !

I currently have a smartbroadband 5g contract with Telkom which expires end of November 2017. I have been trying to upgrade my contract since September 2017 and every-time I go into the store or call into the call center I am told a different story, in September I was told that my paper work was submitted and they are awaiting confirmation, once finalized I will be contracted with regard to my device being delivered, after 2 weeks I was not contacted, when I went into the Alberton store I was told that I do not qualify for the deal and if I want it I will have to go cancel my contract, pay a R800 fee plus a R150 admin fee and then get the new contract. Then i was advised by the manager to wait until October to get and upgrade which I did and went into the store again. I was then told by a customer service agent that he cannot access my account details because I have been ported to the new system which the store does not have, he also reported that he will contact whoever and when their system is upgraded he will contact me, which I waited for until the second week of October only to be told that the only store in Gauteng that can assist me is in Springs. How is it possible that Telkom can port people to a new system without notifying a customer or updating all their stores first???? I'm absolutely disgusted by the service I received these past 2 months. I will never recommend anyone to take a contract with Telkom. I have submitted a case as well in September which also has not been resolved. I get put through to the manager who also cannot assist. I'v sent through a cancellation letter twice already and I have gotten no response back. If someone can assist me with a way forward it will be highly appreciated!!!!!!
