2 months no repsonse - calls logged everyday

Case number : 202crk200915 logged 20th September now 3 November - Line not working - have called everyday to be told it is being escalated! Even stopped a Telkom Van and asked him to assist - saw he actually had our case written down but was crossed out?? Really don't know what to do any more, Paying for a service we are not getting - very frustrated - wish there were alternatives ! Can't stand sub zero service!
